    Last week I sent mine back. Mine wasn't as cold as yours (I could get light vapor, pretty sure yours couldn't get even that), but I never felt I was getting the results that everyone else was raving about.

    After three weeks of not knowing for sure if mine was cool or if I was just expecting too much, I sent it back to them.

    @WildChild all I can say is I hope you have the same experience I did. My replacement is a totally different beast. Unlike my first one where I had to preheat for 15 seconds or more to get any vapor at all, this new one needs only a couple of seconds to preheat and throws much denser vapor. My last one I had to hit it for the entire 30-45 seconds until auto shutoff every time to get hits. This new one I worry about combusting if I hold the button down for more than 10-15 seconds or so. It's nice to feel like this thing has too much power, unlike my other one that felt like it had too little. I no longer feel like I have to do everything perfectly just to get light hits.

    So now I'm re-learning the FF from scratch after owning one for a month :lol:

    But it's a much quicker learning curve with adequate power. I'm no longer just trying to get vapor from it, now I'm trying to get the best vapor from it.

    So glad I finally decided to swap mine up. The verdict is in: it was not producing as much heat as it should have been.

    Keep in mind that there have been a small number of returns compared to the amount of sales they have had overall. Sometimes it may look like 'everyone is complaining' when it really isn't the case. It's just that most people get vocal if their vape is malfunctioning, but keep more quiet if it works great. I don't consider it 'complaining' so much as searching for information about problems. For the amount of fans in this thread, I feel the number of problems is rather low.

    As one of the people who had a return, I would hate to think you might decide against the Firefly because of the posts I made in this thread. I can tell you the following:

    My RMA number was very low. They have not had many returns.

    The process was so painless it was not an issue to me. I mailed them my FF on Monday, had a shiny new one in hand Friday.

    Even though my Firefly was not performing optimally when I got it, I still loved it. I hesitated to send it back because even at its lower heat I used it a lot.

    I missed having my FF immensely for the 4 days I was without it, and when I got the new one I found out that the FF is even better than what I originally had. I love the Firefly even more now.


    Simply put, this is a great vape. Every person's criteria for what they want in a vape is different, but I highly recommend the Firefly if you think it will fit your needs. I would not be scared off by possible problems, and I'm someone who had one of those problems...

    No external temp sensor doesn't mean no sensing. The processor is clearly tracking and regulating the current. And what sensors exactly do you see on other units?

    I don't think the battery is crappy at all. Any battery has finite capacity. If you're heating air with 50 watts, it will need recharging pretty fast. It seems well-sized for the bowl size.

    Now as to whether it's worth $270, the market decides. I paid $260 grand total for mine with an extra battery, and I don't see anything a lot better and cheaper. No question all these devices are overpriced relative to say a cell-phone. But the FireFly's solid aluminum body and screwed together parts are not mass-market stuff, the device is more like a hand-assembled crafted object. I find a MFLB at $120 much more overpriced for what it is, and what it's made of.

    I don't really care for that last fractions off the buds, I like the more cerebral first fractions. I suppose if I wanted black ABV this would not be my vape.

    It's not the ultimate, nothing is. I would love if it hit that coil 3 times harder for a couple seconds then backed off. But thermal realities may prohibit that. The next version? For now this is delicious.

    I wonder if the Ploom 2 runs hot enough for our needs! That one is $40! I saw some people gave up when they saw the manufacturer's site saying it was for their cartridges only. But has anyone tried, either by filling little aluminum "carts" or otherwise?

    BTW, we do need pix! So, am I done here, or under or overcooked?

    [​IMG]

    Before I opened and touched up the position of my coil (a half hour and very simple job, just delicately changing the way the coil was resting), I was getting a lighter ABV. It made a difference also in how easily we get to that blessed plateau where the thermal undercarriage and bowl are humming warm. With a little screen "hat" the ABV is darkest in the center, needs stirring. It's more even if it flies around, but with small loads like this it's more practical to restrain it a little.

    Its my one week anniversary vaping with the FF, and it has been a very interesting experience. I still have combustion expectations for my vaping experience, and the FF HAS DELIVERD:tup:. Those who question if the FF can get to those high temps trust me the FF gets real hot. I hate hitting my FF cold, I have found myself using the button like a lighter. I push it and hold it as long as I need to heat the bowl to get enough vapor to fill the room full of clouds. There is no one way to hit the FF, it all depends on what the user wants. I have read about the button issues with the FF and I'm lucky not to have experienced any of those issues. Its not unusual for me to prime the FF on a cold start, so I'm using my button alot. The FF is built way tougher than it looks. Since its built like a cell phone it would be nice to have a leather case for it. Which brings another point, the FF is the kind of vaporizor that should only be used by one person, and not shared. Its made like a cell phone for a reason, its a very personal device. You don't see people sharing their smart phones, and that's how personal my FF is to me. I love my FF:love: and she is only for me! Everything is not meant to be shared :myday:

    I had a personal discovery with my Firefly. I had been experiencing some harshness in the draws from my Firefly and I have heard others mention this also. I found a solution at least for me. I found that the more fine the grind the harsher the hit. Now I am down to a rough finger shred and my hits are very mellow for me as I feel they should be. Just wanted to share this.

    I find that a coarser grind adversely impacts extraction. I get fewer hits and less even browning. Medium to fine grind for me.

    I get thorough extraction without "working too hard" because I draw slow and steady.

    My battery cover slips off too easily...when I'm replacing the top cover, handling the unit itself, etc...

    I have started shortening the "button press" phase of my draw and extending the "post button release" portion of my draw, and so far I have gotten the same great results. I feel that there is a point at which additional power to the coil no longer benefits the process.

    Comparing my technique to Vitolo's video, I would say I invert his ratio of pressing/releasing.

    I've said it before...my unit seems to produce the bulk of the vapor after I release the button. I let it go and just keep drawing and drawing. I feel it as it gets hotter and denser, plateaus, then tapers off.

    By then my lungs are bursting and my eyes are bulging...

    Edit: I've never had any "snacks" with the FF.

    I only have to hold my power button 5 seconds before I start my toke. :shrug:

    The color of my FF ABV is also quite deceptive. It looks lighter than I think I'd want, but when using the ABV in my Ascent, I find that there's actually very little left, unless you're looking for the hardcore body stuff. And even in that respect, what I get out of the ABV is not very satisfying in any way other than for falling asleep. I get pretty much everything I want from the herb out of the FF, despite the ABV's shade of color.

    And I love the "up" sort of feeling that it gives. Even when using my Ascent at 370, I tend to get more of a "sleepy" feeling than I'd like during the day.

    Also, some strains that work great in other vapes don't work well at all in the FF.

    Anyway, still adoring my sexy beast, even though I think it may be one of the cooler-running units. I prefer it that way.

    Just thought I'd check in. :cool:

    Agreed. It's a Torx 5 for the port assembly and a 6 for the main body. :tup:

    Please do not over-tighten the port assembly screws when you put it back together or it can deform/sqeeze the rubber seal and make it not sit properly.

    Good luck.

    I've ended up waiting a bit longer than expected for my HI, so I've been using the FF as a daily driver for a couple weeks now.

    A while back, I was convinced that the FF would not be satisfying as a daily driver, but only as a portable or to augment a desktop at home. I have now changed my tune because using the FF all day has been both satisfying and ... might I even say a joyful experience?

    No throat irritation at all, even though I tend to need water for other vapes. With an extra battery and external charger, I'm never waiting. It goes with me all around the house and all around outside the house. I'm becoming more convinced that the FF, while expensive, is definitely a two-fer, which to me makes the price seem fair.

    In fact, the past couple nights, I haven't even bothered with my usual Ascent 430 F sleepytime knockouts. I just finish off a bowl as far as I can in the FF and ten minutes later I'm ... :zzz:

    The FF is starting to feel as though it was designed specifically for me...

    I decided to take apart my original 'cool' unit and inspect. Disassembled the heater core and noticed my coil was touching the ceramic top plate at one side, but not the other. I carefully adjusted the angle of the heater coil so that it was in contact along the full 1\2 top perimeter. I also aligned the groove in the ceramic plate with the top groove on the ceramic housing surrounding the heater coil. Put it back together, loaded and gave it a go. Combustion after the second button press and draw. A few more tries resulted in the same. Now it was too hot! Took it apart again and slightly lowered the angle of the heater coil. Reassembled and tested it out. Holy shit...perfection. Half the button presses of previous sessions, huge clouds and even, very DARK abv. Fuck ya!

    (No pictures, sorry...)

    My buddy loves the replacement I sold him and I now tweaked my FF to work for me...albeit by chance partially.

    I cannot recommend anyone try this as I don't want you to screw your warrantee...I risked it and things worked out.

    I apologize to @Vitolo for my rude, defensive response several posts ago and to you all for my negative initial review.

    NOW I can share in the joy... :)

    Wow! Nice work! Glad that ended up well for you. I personally would be scared shitless to try and tweak the coil. I'm sure I'd screw it up, or break it, or something. If this were my FF I'd just spend 10 bucks and send it to FF to fix, but again I am all but assured to mess this kind of thing up. It's actually surprising that such a small positional change would have such a dramatic effect, but I guess that explains the variations we are seeing reported from unit to unit...because I can see how easily the coil's position might be a teeny bit different in some units, despite quality control. And that could explain why every unit seems to have a bit of variance.

    Which leads me to Day Five with my new Red FF. I have noted the following differences over my Silver FF:

    • Battery cover fits more snugly. The silver's didn't come off by itself or anything but had a slight play in it, side to side, at times.
    • Heat button is weird. I'd almost call it "mushy"...sometimes it's tricky to feel the detent position when you push it in. It never fails to work, but I'm a bit alert for issues with it. Hopefully it won't cause any operational problems. The button on the silver unit had a weird side-to-side play to it. Also weird, but different weird.
    • Heat shuts off after 30 seconds of holding down the button. The silver shuts off at 45 seconds.
    • Overall, a touch cooler, or should I say it cooks in a smoother, less heat-spikey fashion. ABV is almost always very even, almost never see any charred bits. Basically it's getting to the same temp and level of extraction, but it takes longer with the button to get there, particularly in the back half of the session. I have a feeling this one is calibrated the way FF intended, though the silver worked great...It just got hotter faster and so technique differences are required between the two FFs.
    Be interesting to see what I get back from FF...if they replace my silver one, the new one may be more like the Red than the old Silver. And if they tweak/repair the Silver, that could affect temp profile also (in fact it absolutely will). Life is never boring in FF Land.

    Bottom line: Red FF is gorgeous, works great, extracts as well but more smoothly and evenly, and is noticeably different than the Silver.

    The screen is JUST large enough so that the edges slot a touch under the bottom edge of the glass bowl. One tip to seat the screen: make it into a dome, so that the circumference is smaller than the surface of the bowl. Place it dome-side up, and gently press down till the edges of the screen slide under the bottom edge of the glass bowl.

    It's pretty odd that the O-ring came out from the bowl...I clean mine with some paper towel damp with iso and so far haven't caused the ring to pop out. (Very weird...must have been some circular play in your bowl, which is strange because the bowl and heater assembly are held in place by the pressure of the top plate.)

    If you didn't seen these excellent tear-down pix, check 'em out. You'll see the black O-ring in several of the shots around the top edge of the bowl. I assume it's there to make a solid seal between the bottom edge of the steel plate and the top edge of the glass bowl.

    Here are a few of the positives and negatives I have experienced with the FF over the past few weeks. I do love this device and when I am getting good results, the positives heavily outweigh the negatives.

    Positives
    • The device itself looks and feels like a Rolls Royce. It really is kind of a trip just using it and holding it. At times, I feel like I have a crush on it. My wife catches me all the time just trying to talk about it.
    • It is very efficient on herbs. Great way to conserve. Can use only small amounts when you want to and that is enough for a head change
    • It is absolutely capable of giving extremely large, bong like hits that really knock your socks off.
    • It is pretty intuitive, you can start getting good results right away with no experience. I had absolutely zero vaping experience before this and was able use it very effectively right out of the box.
    Negatives
    • In my experience I have found it be on the inconsistent side. Just when I think I have my technique down, all of a sudden it is not working anymore. For example, I have had the FF 3 weeks now. I have been able to produce huge satisfying hits on the first few draws pretty consistently. Lately the past few days (about 15-20 bowls) I have not been able to produce the same large clouds and have been left very unsatisfied at the end of every bowl. This can be very frustrating.
    • The battery life is a little annoying, but if you have the external charger and extra battery it is not a problem at all. But you are always making sure that one is being charged all the time which can be annoying as well at times.
    I admit this device has had a lot of pressure on it. I went from not having any vaping experience to taking this thing home to be my one and only device to be used throughout the day and night. So far it sure has been a rollercoast ride:rofl:. A true love hate relationship! I have been hanging in there, but at night time I do miss a couple of good ole bong rips to the face...

    Posted this in the toronto vape review of the Firefly. Let's see if they approve the comment...

    "I have been using my firefly for several weeks and need to correct you on several points.

    1. It is not similar to the Magic flight. The Magic Flight is a conduction vape. The Firefly is a convection vape. It only heats your herb when you are drawing through it. That is a HUGE difference in flavor/amount of herb used. When I am vaping I do not want my herb heated constantly at high temperature. I like to be able to vape and wait a few minutes before my next vape.

    2. Have you figured out where the heft comes from? It is because the body is powder coated aluminum not plastic as you have reported falsely. This not only gives it a nice heft it acts as a heat sink so that the unit remains comfortable to hold (an intentional design feature). Some people just love the nice weight of it in the hand, it feels solid and well made. And the finish is without equal.

    3. Your comment about magnets losing heat. I work with small electric motors that generate a lot more heat than I have been able to feel on my top plate and they have been fine for years of service so I doubt the magnet is going to die any time soon. Making statements like this without testing are not responsible for a reviewer. Especially when it is stated as a fact, not an assumption.

    4.You state there is no temperature control but the Firefly website says that the unit is computer controlled to a maximum of 400 degrees Fahrenheit. Yes I have been able to combust a few times with my Firefly but it has been rare (2 out of 100+ bowls) and each time it has happened because of a tightly filled bowl, a slow draw and multiple button presses during the same draw (my girlfriend). New users often spend too much time preheating and draw too slowly. If the button is then pressed a second time the heat cycle starts up again which is computer controlled to give a higher burst of current in the initial stage. If the temp was already about 400F then this can lead to combustion.

    5. Yes the firefly has its issues. I agree the battery is too small, perhaps a change to 18350 battery cells or other commonly available vaping batteries would alleviate this problem. I purchased mine new with battery and charger for 300 so it is very easy for me to just rotate batteries when at home, or to take another battery with me on the road. The two batteries have been more than plenty for out of the house. As you perfect your technique you learn to not preheat the bowl and to draw for four or five seconds then let go of the button and draw for several more. This really helps on the battery efficiency and gives great taste and vapor.

    6. The firefly can be very discreet. It is about the same length as my iphone 5 in case (5 ½” for iphone in mophie case 5 3/8” for Firefly) Width is 2 ½” for iphone in case and 2” for Firefly. I use an overhand method that covers the glass and makes it look like you are just sitting with your phone under your chin thinking. The firefly looks remarkably like a nokia phone. I have walked in public with it to my ear talking as a joke and no one gave a second look.

    So in conclusion as a reviewer I feel that you have misrepresented some facts here and I am trying to correct them. I am also giving a different viewpoint on some of the features that I like in the Firefly. I am no noob and this is my favorite vape. And I love the glow! That is more important to me than a digital readout. The Firefly feels very analog. It is easy for a noob to use immediately and can take weeks to master fully. That being said, as with all vapes it is a matter of preference, YMMV, and I can’t wait for a second generation with a better battery system!"

    Well, it looks like I will be getting a replacement for my Silver FF. Just heard back from them, and they wrote that they looked at my FF and determined it has "a misaligned heating coil, and will need to be replaced". This makes me think...a. anyone playing with their coils had better be careful, because it can obviously have dramatic consequences...b. HOW did my coil misalign? no idea. Worked fine for months. Maybe it was always misaligned? and c. I'm wondering why that kind of thing can't simply be repaired, instead of replacing the entire unit.

    This also reminds me that the guy who posted the original teardown pix, and even removed the circuit board, did say that he didn't dare try to move the heating coil even a little bit. He was obviously rightly concerned about it. So those of you tweaking the coil, keep in mind it not only potentially violates the warranty but also can create all kinds of problems if you cannot re-align it properly. Caveat Modders!

    UPDATE -- Going on 1 month since our first "date":

    Thanks to all the good technique tips from FF owners on this forum, I've begun to learn the ropes with my lovely lady. Here's what's working best for me:
    • full oven, lightly packed coarse ground herb (2-3 turns in my SpaceCase grinder)
    • heat button pressed for 6-7 seconds, draw for ten seconds
    • consider the first draw as "throw away" -- I think someone else has already mentioned this
    • next two pulls (within 60 seconds of the first) with 5 second pre-heat, 10 second draw, heat off, continue pull for 3 more seconds
    = good amount of vapor and thinnish clouds

    That's usual enough to get me going for a couple or three hours. (I'm not a heavy user).
    I then stir the load a bit, getting things set up for a 2nd session later on.

    I like to refresh the oven contents after a 2nd session and re-charge the battery every 2nd or 3rd session.

    Still experimenting with various strains and methods of packing, and no longer worried about having a "cool" unit.

    Lovin my FF; life is good.

    I'm having a wild ride with my new Silver Firefly.

    I previously reported that my new silver unit was functioning exactly like my first dark grey unit. Eventually I started noticing that it was a tad warmer than the grey one. I also noticed that the gap between the glass bowl and the metal plate seemed bigger on the silver unit, allowing more material to slip under the bowl, past the screen, and onto the metal plate. So I decided to try changing the screen to see if a different one would slide around less inside the bowl.

    That's when the combustion started :(

    I was using my normal technique and...flash of flame (visible even above the FF glow), acrid smoke, nasty burnt cherry in the bowl.

    Well I snuffed it out and set about cleaning the Firefly to try to get rid of the smell. I chalked it up as a fluke until two sessions later - flames, smoke, cherry. I had even backed off on my button press time to prevent it from happening again!

    Not to be deterred, I cleaned the unit up again and got ready for the next session.

    I had been using 8 second button presses after the first draw, so I figured I would cut it down to 4 or 5 and see how it went.

    One-one-thousand...two-one-thousand...three-one-thousand...four-one-th...COMBUSTION!

    Again flame, smoke, cherry!

    Frustrated, I took the top plate off, lifted the bowl assembly off of the ceramic components, and tried moving the coil around slightly (and gently). I cleaned and reassembled the unit with a different screen. After tightening the top plate the gap between the glass bowl and the bottom metal plate seemed somewhat smaller than before, with the screen fitting a little more snugly. I've run several bowls through it since, and have not combusted. I am still using much shorter button presses than before though.

    It really seems to me that the combustion started after I changed the screen. I was careful not to apply too much pressure to the other components when doing so, but it still seems to me that changing the screen somehow changed the way the unit worked. It seems to be almost a completely different vape than when I got it.

    Something tells me that there are ways that the Firefly performance can change, depending on how things are put together, how the screen sits in the bowl, and how much of a gap there is above the metal plate. All speculation of course, but something changed in my Silver unit.

    I could go on a HUGE list of reasons why that vape is on the top of my list of least favorite portables...

    BUT to stay on topic I'll throw some things out there that the firefly does FAR better.

    1) Tastes good
    2) Safer design
    3) Better customer support
    4) External hotswapable batteries
    5) Cool vapor...WITHOUT needing water
    6) Pocket friendly, no glass shards in your pocket...whoops!
    7) Stealthier in usage
    8) Visually far more appealing
    9) Can take single hits whenever you want. 1 minute bowl is easily possible vs 11 minute arizer sessions.
    10) 0 second warm up time, heat on demand no waiting.
    11) TASTES GOOD

    I mean if one person can declare a vape "no good" based on their opinion, there are NO good vapes out there period. There is no vape that is universally loved. The firefly is the overall best portable I've ever used personally. There are many others who feel that way.

    For the record I've never stirred my firefly once. I either shake it gently once, or if I placed a full nug in the chamber for the first hit, I'll open it crush that in my hand and sprinkle it back in. Its not efficient to throw in a solid nug, but it tastes so good that I do it for the first hit a lot of the time. Then I crush it up to make it have more surface area and vape better for the remaining hits.

    Yes, if I draw at my Firefly's "natural speed", without forcing it, I feel like I'm sipping through a very skinny straw. I feel uncomfortable, like I'm running out of oxygen unless I allow some air through my nose or around my Firefly's mouth piece.

    If I really suck hard, its better, but I don't think I'm supposed to do it that way, and the vapor seems kinda weak.

    And, yes, I do let it preheat for a few seconds before sucking. I tried pulsing it, but sometimes it partially scorches. One thing I like to avoid is when parts of my bowl scorch, and then the whole bowl smells and tastes like popcorn before its time.

    As long as I don't want to smoke something different, that works fine.

    But, if I want to stop smoking XXX, and switch to YYY, I'm out of luck. I'm reluctant to dump a half-smoked bowl, yet its not what I want at the moment. I guess I could try to store the half-smoked flower someplace...but, seems kinda messy and awkward...

    A big difference that I can see between the Firefly and the MFLB:

    The Firefly uses heat stored in the heater core to produce vapor even after the user releases the button.

    I am still getting a significant portion of my vapor after I release the button. In fact, at the end of a bowl, I can often get one full hit without pressing the button at all. This is just using the heat stored in the core. I wouldn't say it is a huge "cloud" hit, but definitely visible vapor.

    To the poster earlier who was drawing 3-5 seconds after releasing the button I say draw a LOT longer than that. See if you start getting vapor after releasing the button, but with a much longer draw.

    @Vitolo - Even though I have pointed out some of the less desirable aspects of my Fireflies, I would still say they have both come a lot closer to "perfect" than most of the other portable vapes I own. Great build quality, and excellent results.

    I was intrigued by ElPic's suggestion so I ordered a three pack of the Iolite Wispr screens from VapeWorld. In general I have had no luck with any non-oem mods I've used on the FF...the Arizer baskets ruined the taste for me, a top screen seems to make the chamber too hot...but I figured the worst case scenario was losing 17 bucks.

    They arrived yesterday, and man, what a find. They fit perfectly. They don't seem to add any heat (although I haven't used it yet on my Silver, just my Red, so I can't be sure what effects it might have on that particular device, though it fits both perfectly.) It keeps the floor of the bowl clean, eliminates the need for the bottom screen (and the attendant issues with removing, and re-installing the screen), keeps fine debris from slipping under the bowl edges, and in general makes the bowl much neater and compacted material doesn't build around the edges. It also pops out easily.

    Doesn't seem to be a downside other than making the chamber slightly smaller due to the raised nature of the screen...but I didn't really notice it forcing me to use any less material. Overall, an *excellent* upgrade to the stock screens, the first non-stock thing I've done with the FF that works well for me, and I like it so much I'm going to order another half-dozen. As I said I need to see how it works in the Silver, but so far in the Red FF it's a stellar addition. Thanks to @ElPic for the awesome idea.

    The Firefly is outstanding, I love it. It took me a couple days to adjust my technique, but now I think I have it dialed in. I found it fairly intuitive, and as always the collective dialogue here was very helpful.

    I am now using a slightly courser grind than I do with my other vapes. Initially this was just to keep the airway clean. Normally I would assume that a courser grind would result in diminished cloud production, but in this case I'm not really sure. I haven't gone back to using my normal fine grind since mastering the heater, but as it is I am getting nice enough clouds with the courser grind. I haven't run the heater all the way up to its cutoff time yet, meaning I could push it a bit harder, but haven't felt the need to. The most I have held the heater on is probably about 20-25 seconds, which includes my 4-7 second pre-heat. Less time on the button with subsequent hits, as the unit starts to retain some of its heat. It is also sometimes nice to just sip on it for a few seconds and not chase clouds, although this is not usually my first impulse with vaping in general. I like clouds.

    I like the bowl about 3/4 full and quite loose, so the material can be shaken/stirred around without opening the lid, either manually or by drawing. Packing down or overfilling the bowl results in uneven heat dispersion and makes it difficult and messy to stir the load. Even with stirring the load it comes out spotty. With a loose bowl and a couple shakes, the AVB is perfectly even. By the end of a session, I have no problem getting it as dark as I want it. It's all in how you operate the heater and how you draw.

    I have a very small gap in one area where the glass bowl meets the bottom screen, as some others have mentioned. Small enough that not much will get in there, especially with the courser grind, but surely over time some tiny particles are going to collect inside the unit. Not sure yet if I will bother with the Wispr screens or just leave it to fate, or possibly try molding a screen myself. The 5 year warranty is reassuring, and if I really wanted to, it looks easy enough to get under the faceplate and spruce things up. Not too worried about this one minor issue.

    I have also been experimenting with using a top screen which is flush with the outer diameter of the glass bowl element. Pressed down by the Firefly's lid, it is successful in keeping most debris out of the airway without noticeably affecting the airflow. Others have said they thought using a top screen may have been resulting in higher load temperatures due to increased thermal mass. While I'm sure this must be true to some extent, I'm not sure how significant the increase would be. I will try it again without the screen now that I have the heater figured out.

    But...NEVER use a 'canned' air duster on any vape because they contain a bitterant chemical that can foul the flavor of your vape for weeks. My duster is electric to avoid this very situation. I seriously fouled a davinci using canned air that contained a chemical bitterant that I was unaware of. DO NOT USE CANNED AIR DUSTERS FOR THIS.

    I have been using a top screen, on occasion, on my Red FF, which (also on occasion) seems to run a little coolish. I find the screen makes the unit run hotter, and allows me to extract more of the final vapor hits. I don't usually use it in the first half or so of a bowl, only if I'm having trouble getting the latter half to really extract to a darker color. I think that's why you're getting bigger hits right away...the screen seems to raise the heat level a very small but noticeable amount.

    You may find the mushiness goes away after a week or two; I had this experience with my Red unit. After some use it became much more "authoritative" when pressed.

    Moving from a medium grind to a fine grind (with a trusty topscreen) changed my entire Firefly game. I do still hand-grind, not to dust, but just fine. When using a medium grind, I experience much more resistance, "heat tunneling", and general lack of extraction.

    Im no expert, but from what I've observed, and even read in this very thread, decreasing the surface area of the herb particles greatly increases heat distribution and vapor extraction. And someone just mentioned pulling too hard doesn't let you get the highest of temps and best vapor.. But I seem to be having an opposite effect.

    Since grinding finer, my draws have been smoother, producing much more vapor with less lung power. If I draw harder Im not experiencing low temp issues at all, in fact it only results in large mushroom cloud hits that make me cough and give me a head-change. But.. Im not always after that. I can pull steadily, almost gently, and consistently get substantial vapor until its completely milked to a dark brown ABV.

    Again, this may just be my strain, and others may work best with a medium/coarse tear.. But you should at least try both ways yourself and make sure.
