I too experience the buzz. I have something similar happening to one of my box mods for vaping ejuice that buzzes as well. From another forum they discuss battery interfacing with circuitry.

'MODs deliver Quick / Short pulses of DC voltage to the atomizer, and "sometimes" can be heard as a slight Buzzing sound ... Its because PWM (Pulse-width modulation) technique on this particularly circuitry."

It's a tempeture control mod but wouldn't one think the the same applies to the FF2?

Now, this is just an assumption but sounds logical. My other box mods buzz or hum because of the same thing and when I look up reasons for them the answers are similar ... the pulsating DC voltage.

If someone else has another idea we'd love for you to share.

FWIW, in the grasshopper thread they had mentioned a buzzing sound as well remember when I read it. Similar situation? Would someone with a Hopper care to confirm?

Thanks and hope some of my info is correct and helps.
We used to call this duty cycle variation using a chopper circuit. This is how to vary wattage. Probably hearing the chopper, but you should not, in my opinion, on a well designed circuit.

Perhaps a more current EE can comment?

OK I can clear up the buzz issue that some folks are noticing. According to FF the buzz is normal, part of the physics of using a coil....not everyone hears it, it varies a bit unit to unit, but it's totally normal. Apparently it's similar to the sound of an incandescent light bulb....I vaguely remember what that sounds like!:p

So no, you guys aren't crazy. But apparently I really do have hearing loss in those frequencies. :lol:

Does the oven from firefly 1 break easily ? Is the oven for ff2 redesigned ?

Yeah speaking of coils, the FF1 had a few coil failures. I had a few myself. The 2 has a re-designed heater that is installed with tighter tolerances. Theoretically shouldn't be as much of a failure point in this version.

because i've read some people bought 1-3 lol

im thinking of getting this but afraid of good design but easy breaking

$300+ is a lot of change for a portable

Hi all, total newbie here on this forum and I have a question I haven't seen brought up for the FF2 yet. In researching this vape, some original FF users used the arizer whip screen in the FF bowl. Have anyone tried that with the FF2? I like hiking and toking on the go and idea of using the arizer whip screen and the Vapir No2 screen to pre-pack a few bowls would be awesome.

Yes, that's exactly what it sounds like. I was just alarmed because it started getting louder recently. So it couldn't possibly forewarn of any electrical failure?

Is anybody else hearing the slight buzzing sound when ur unit is activated? you would need to hold your vape next to your ear. I have a hard time buying the whole "it's normal, but only three people are hearing it" explanation! The noise doesn't go near the range of frequencies that are inaudible to human ear, so saying some people just can't hear would be a silly excuse.

yeah and the thing that bothers me the most about it is that initially the sound wasn't there

FF is telling you it's normal. It's not a symptom of fault or impending failure. It's normal. You guys were concerned, I was able to ask them directly about it, and was told by the guy who designed and engineered the device that the slight hum is normal. (Go ahead and take a hit everytime I say "normal". :lol:)

"The buzzing that people are hearing is normal. It's part of the physics of using a coil and it's a similar sound to an incandescent light bulb. It's there but not something most people will hear unless they're really listening for it. Unit to unit the frequency will vary due to the electronics timing variations but it's not a problem or the unit doing anything bad."

That's the exact quote. If that verbiage from that source doesn't alleviate your concerns, I'm definitely out of bullets. :p

Btw I finally heard a slight slight hum in my FF. I had to go to the quietest room in the house and press my ear directly against the unit. If I lived a thousand years and owned a thousand FFs I never would have heard that sound in anything approximating normal usage. :2c:

My unit arrived over the weekend but I haven't had a chance to use it until tonight.
So now I'm too medicated to report anything of much use. It certainly does seem to get the job done.

@C4PO Heya, I'm on a Huawei nexus 6p and I have had no issues with bluetooth, running fully updated 6.0.1 with location turned on. I can pull the battery from my FF2 mid use, then slap another in and the app auto connects and I'm off to the races.

@hi_there that's normal base charger noise, if you put the charger to your ear with the FF2 on it, you can hear it clearly, I reckon it's just coil whine, it depends on the wattage you pump into it (which power brick/usb used). I bought a 20w tablet charger and the coil whine is low volume but high pitched, charges batteries in 30 min flat! and everything else I own is charging faster now too, no more waiting for my vape mods to charge 18650's

Good to know, thx! I'm 90% sure my problem is the Android N Preview. Maybe I'll flash back to Marshmallow, but that's a PITA. FF2 is still working great on default settings for now.

I now there are some musicians out there with frequency hearing loss. I am one of them...been playing music for almost 50 years and there are some frequencies I use to hear but cannot here anymore, maybe a version of tinnitus(Eric Clapton has it),ringing of the ears. Anyway, I just put my ear on the FF2 and I hear a winding hum when I fire it up. Never thought about this noise until now. No big deal for me though.

If you just read this page, you'd see an explanation for this behavior. You don't have to read the whole 100 page thread. Or even several pages. Just look a few posts above yours.

Just to save anyone else time posting, yet again, about this humming sound, read this page.

Well, I spoke with FF. It was a very non productive conversation. Basically they think there is nothing wrong with it, and that the factory smell/taste I am smelling is normal. I will come back and give a more descriptive detail of the conversation.

@huxley
I appreciate your investigation...

I did notice a faint smell when I got mine but was not too bothered by it. And before I saw the vape taken apart I assumed it was just the lid... but I'm not sure now.

From my tests the air does get pulled through the bottom lid, battery area and the charging holes in the lid. And these air paths are clearly visible from the image I reposted from Reddit. I also believe this is the whistling heard depending on draw speed.

I am disappointed that for 330$ a vape would leave the electronics so open.

I just don't understand why they would even consider building it that way...

In terms of vapor I love this thing... in terms of health who knows.

I can say because of this I probably won't purchase another ff vape in the future. But in the meantime it's quick and easy and the best vape for my usage.

The technology seems on point but to me it feels like it was put together with money on the mind.

@snamuh I agree with you 100% on all your points. I was/am very disappointed with the FF2 open circuitry vapor path and resultant stink.


.....................................................................................
I do not own a FF2 but very interested in it.
Just my experience with new vapes--I find many many have a "new vape smell", not a good smell (like new car smell?).

Hard parts get cleaner with ISO and then Dawn detergent and hot water. they could have machining oil, mold release agents, etc.

Silicone gaskets etc (soft parts) get cleaned with Dawn and hot water. Best example for here is JyARZ which had a batch of new material gaskets that smelled, to some people. You could air out but I did Dawn wash and it got rid of 99% of it. You might consider a good cleansing or a repeat cleansing to help snuff out the odor

Thanks @MinnBobber for the good cleaning tips. Unfortunately did not work for me.

I got mine on Friday, and my experience is very similar to most others I think. Some notes:

- I did have chemical taste for first couple loads, even after first cleaning with ISO and letting it air out until I could get home to try it out. This has gone away now after about the 4th load.

Thanks @C4PO Interesting that you ISO cleaned it and yet it still had the chemical taste prior to the 4th load. Glad the smell has now gone away after the 4th load. So have you now re-ISO cleaned it? If not can you do that to be sure all herbal flavor is gone and redo your taste test on Med-High and Concentrate mode?

eeeehhhhh, not buying the bit about hum being normal. Comparison to electric light bulb is misleading, the light bulb runs on AC current, not DC. Don't hear humming from flashlight bulbs, right?

I hope everybody's unit is just fine, but changes in behavior (not humming but now it is) would concern me.

I'll do an ISO clean and let you know. Stuck on med-high for the moment though due to my Android issues.

Completely separate question... What is the best way to store any reclaim oil I might get?

I did two small bowls last night and I am pleased and find it very easy to use.
However mine does have the slight chemical taste/smell. I liken it to when I paint a room in the house, there is that fresh paint smell in the air and you can taste it. I am glad to read that @C4PO says it went away after 4 loads so I'm planning to wipe it clean with ISO tonight, let it dry and see if it improves. If it never goes away, that would be problematic, but I hope that wont be the case.

I cannot believe how light it is, almost a toy compared to FF1. This one heats up super fast, I
found little vapor with the first two hits but a much denser vapor by the third hit as it heated up. And of course, as I just read in the manual, draw longer for denser vapor! I certainly felt the full effects of medication last night!

I think this is a device you play around with and find what works best for you, sip small hits or longer draws for bigger clouds. Personally, I'm not so worried about clouds, so long as I feel the effects.

Duh moment, while admiring the glow of the bowl I realized why its named the firefly. Captain clever over here has only owned the FF1 for about 2 years.

I do like the way the glow lessens as it heats up, for whatever reason I find that kind of neat.

I will report back on the progress of the smell/taste situation.

No worries. It is indeed a typo. You will only get four flashes no matter how full you try to charge the battery. The blue battery light will not flash five times.



Honestly, while the FF does better with longer draws, you should be able to get substantial hits sub-10 seconds.

1. Pack the bowl pretty densely.
2. Start your temp on HIGH.
3. Pre-heat for one full cycle.
4. Start hitting on the second cycle.

You should be able to get good hits in under 10 seconds with a little practice. Good luck.
I think you are spot on about the longer draws. I can't physically can't take them and don't get good results. Just put mine up on eBay, too bad as the flavor really is fantastic. I'll look to other brands in the forum as this was my first vap...more asthma friendly. Thanks to all who gave me tips, very much appreciated!!

As a smoker, I was primarily a waterpipe/bong (ice cold water) guy but also dabbled in bowls for on the go or low maintenance, no frills usage.

Unlike a lot of new firefliers, I got my first vape around 13-14 years ago. When I used to grow a little, I picked up one of those crystal-ball-looking things with a soldering iron in the middle to try and sample flowers early to get as sense of what they’d be like. (yes, a great idea, like brewing green coffee is a great idea.) Either way, that crystal ball thing was trash.

Years later, I picked up a Volcano. My girlfriend (at the time) needed medication for chemo and we weren’t about to smoke regularly to get it. Absolute game-changing device. Love everything about it. Complete 180 on the inhaling experience. Some years later we wanted something portable and picked up an iolite. Still head-over-heals with the Volcano after 7 years. Married the GF. She no longer _requires_ the medication, but we still enjoy it. :) We are health nuts and have zero desire to ever combust again. I only occasionally do it in social settings (ie tipsy) and always regret it the next morning.

The iolite never really did it for us and we mostly just skipped partaking when away from the home sans eatables. Last summer when I had problems sourcing butane for the iolite while in the Hamptons, I decided on looking for another portable.

I’ve mostly been eying the crafty, since the volcano is so strong. I came close to picking up a crafty a couple of times but kept dragging my feet. Once I heard the firefly 2 announcement, I decided it was the one for me. I was primarily drawn by the quick startup time (key for a portable, IMO), all glass path and convection, and general attention to detail. It looked like the perfect bowl to my bong (Volcano).

Now that my autobiography is out of the way, my FF2 experience…

I’ve had the black ‘fly for a week and it’s an exact match for what I wanted. The bowl analogy is so perfect. I can see it is much more than just a portable. It’s an alternative. A different experience than the Volcano. And I will use it as such.

The taste is incredible. Its better than the first bag from the volcano. The feeling is sneaky, because you are getting more out than you think. It can be a quick one-and-done or a 2-3 bowl session. So simple and so clean.

The first few days were variable as I tried different techniques. I landed on medium or medium-high heat, fully packed, level with top of bowl, using torn or rough-ground material. As long as it’s not too finely ground, you can’t really go wrong. Loooonnnng Sloowwwww Draw.

The LSD is the probably the most important thing. On my first night out with the FireFly2, the day after I got it, I ran into trouble. I had been drinking a little and pulled it out for our walk home. For whatever reason I went right to pulling really hard and got no satisfaction. Got home, reloaded and tried again. I hastily went after the second bowl with the same aggressive pull and got crap again. It left me feeling like the pull suddenly became too restrictive. I gave up and hit the Volcano.

The next night with a clear head I returned to what gave me success on the first day: LSD. Since then, its been nothing but great satisfaction and all about refining.

I have to say that I love that I can just pick pieces off and put them in this thing just like a bowl. Really all you need with you is your FF2, a toothpick and some flowers. For the record, I’m getting nice clouds on the first LSD. Actually, the green hit is easily my favorite.

This hasn’t been mentioned much, but I absolutely love the flat glass surface around the bowl. There is so much utility there. For on-the-go, its great to have a surface to crumble and pile up some flowers and then sweep into the bowl. Also, for stirring throughout the session, I pick the material out onto the surface with the toothpick, mix and sweep back in, green down.

The app feature doesn’t really bug me, but I get the turnoff for some. I think I’d be perfectly happy with just the default settings. I’ve tried temp surfing and stepping but it’s really not worth it for me. I’m still on the fence between medium and medium-high. The medium-high will definitely extract the most and provide more satisfying pulls but the medium is slightly less harsh and better flavor with less mixing. I’ve tried finishing on high, which will definitely get you an extra hit or two, but I don’t like roasting things quite that far. I’d just as soon pack a little extra flower to swap out and extract the last bits from the ABV with some oil or butter later as I’ve always done with the Volcano. Also, this thing has a strong propensity to over-extract or even seemingly char material, so upping the temps is not in my wheelhouse. Point is: I don't mind using a little extra material to use the FF2 where its strongest.

Where I’d appreciate some improvement in the device:

As I mentioned, it has a strong propensity to over extract parts of the material. This requires very regular stirring. Very regular. On medium-high, I am stirring, with a toothpick, after every LSD for maximum awesome and still getting plenty of black bits. My first LSD on med-high always produces some near-black ABV. In a way this contributes to the bowl-like style of the FF2, but it’s a negative.

Related: the resulting ABV is not evenly extracted. It’s not a huge deal, but coming from the Volcano which is about as even as it gets, its obvious. It still tastes great for 75% of hits and works very well overall. Like I said, I’m stirring after every LSD and it still pretty uneven.

It’s noticeably harsher on the throat than the Volcano. The ‘cano is about as smooth as possible. It’s like a big bong, filled with ice and water, sitting on a block of dry ice. Actually, its smoother than that. I do find the FF2 much more pleasant than the iolite or really anything else I’ve tried, but at the end of the night/next morning, I have a little sensation at the back of my tongue and throat. Very minor, but there.

The battery cover bugs me. It almost never seats right on the first try. I feel like they could have done better.

I, like most others, would have preferred an external battery charger and a usb port on the device. The dock is junk. It is obvious they went for style points over functionality. The firefly looks much cooler sitting angled on a dock on your desk than it does in a drawer or plugged into your computer.

Due to my technique and some early fine grind testing, I have material wedged around the outside of the bowl and in the bottom of the bowl. It doesn’t bug me that much, but I can’t ever get it 100% clean.

Back to crushing on the FF2… Its really such an awesome little device. I could see it being my one-and-only as unobtrusive-yet-powerful as it is, but it’s such a perfect companion to the Volcano. Most importantly its fun and brings some nostalgia back for this total nerd that left combustion years ago. Love that glow. For better or worse, I’ve had a bunch more sessions the last week than I normally would. This may be contributing to the throat discomfort I mentioned earlier. Having a no-fuss ready-to-go device is outstanding. Its quite discreet where it counts. Smell is low before, during and after usage. It would probably be entirely odorless with a spoof. It's also ready to go and ready to put away at any time. Sure, if its sitting on a table, someone would be able to identify the situation, but I don't feel like full camouflage is necessary to keep things on the DL.

I still, of course, worship the Volcano, but I can be up and pulling on the FF2 before the warmup and grind period are done on the ‘cano. Its also just cool as fuck to use the FF compared to sucking on a weird bag. (I totally love the volcano, but anyone’s first encounter is going to have them thinking you are a nut.)

So, yeah, its been a toasty week, but when I got my espresso machine I was a pretty intense guy for about a week. Boys and their toys, its just how it goes.

Quick tip for those with a partner in crime that gives two shits about the cool new tech: My wife really doesn’t care what we are using and is not a fan of the LSD. She’s used to sipping on the bag and likes that style. I start the pull for her, do about a 10-second slow-draw and then immediately pass to her with my fingers still on the buttons for her to take a 5-10 second slow-draw. She’s getting satisfaction that way. For her the volcano will continue to be her preference, but this is an acceptable alternative.
