I just received a Launch Tube (actually, I ordered two; one standard, and one low temp) and I thought I'd share some of my thoughts. I'm only going to talk about the standard Launch Tube in this message, as I really haven't had the time (or desire) to fool around with the low temp Launch Tube. I plan on playing with it tomorrow or Friday, but from initial experimenting I suspect I won't like it as much as I like the standard version.
First a little background. I have a Volcano Digit and an iInhale already, and I've been vaping for a little over a year. I bought the iInhale the first week it was available, so I've been using it a while. Vaping is not a religious calling for me, though I much prefer it; still, I occasionally enjoy smoking too.
Before I get to what I love about the Launch Tube, I think it's important to say that no single vaporizer type is good for every use, and some vaporizers require you to learn the best way to use them before you can be happy with the results. My Volcano doesn't let me use it on the bus (it's not portable), but it required almost no learning to use properly, and it's still my favorite, by far, when I'm home. My iInhale, though portable, requires a LONG setup/warmup time of at least ten minutes, and no matter what anyone says, it produces enough smell while it warms up that everyone around me knows what's going on (and all the sweet terpenes are going into the air in the room, not into me). So for my use, it's no good if I want a quick hit, and it's not very stealthy if I'm not outside (outside it's great; no one knows what it is, and no one seems curious about it). The iInhale required a LOT of learning to use properly. That said, I don't think I'll be giving up my iInhale now that I have the Launch Tube, any more than I gave up my Volcano when I got the iInhale. There are a number of times when I'm working outside that the iInhale is more suitable than the Launch Tube (or the Volcano).
For me the Launch Tube fills a need that the iInhale really fails at; taking a quick sneaky hit whenever and wherever I want. Even after I got the iInhale, I always carried a (glass) one hitter, so I could grab a quick hit whenever I wanted it, and didn't have the 15 minutes required to really prepare and use the iInhale. But of course the one hitter is smoking, not vaping, and it's a pain to light outside if its windy. I have a tiny padded pouch I wasn't using anymore that I now use to carry the Launch Tube and a couple of batteries, and I don't plan on carrying the one hitter anymore. I am really happy with the Launch Tube as my new one hitter, and figure I'll use it WAY more than I used the iInhale.
The Launch Tube is a true one or two hitter. Within reason, the less you load, the better it works. A pinch or two is plenty, and if you stuff it full, and pack the load into the screen, it won't work as well, and the vape won't be as sweet. Just as important, you really, really want to grind your load before you put it in the screen. It makes a significant difference for the good when your load is ground, as opposed to just broken up into tiny pieces. Placing a single small bud in the screen is NOT the way to go. It will work, but grinding first it will work better. You don't have to grind it down to dust, a single grinding in a standard grinder is enough. You don't have to grind each load just before you use it, you can grind a days worth and keep it in a tiny container if you like, (though as with coffee, a fresh grind is always the best). I keep my preground daily load in a little capped plastic tube I got in Amsterdam that was designed to hold a single joint.
You only have two ways to regulate your experience. How long (and in what manner) you apply the battery, and the rate (and consistency) at which you inhale on the tube. Both effect how hot the screen gets, and how much its temperature fluctuates. When you're first learning how YOU like to use your Launch Tube, it really pays to have good lighting, so you can easily see the vapor stream and the color of the load as it changes. Once you've figured out what you like, you can use the Launch Tube easily in the dark, but seeing what's going on really helps when you are first learning.
The load is going to turn from green to brown as you use the Launch Tube. This change will work its way from the edges of the load toward the center, as the good stuff is depleted. The load will NOT turn from green to brown uniformly. Note that at no time does it ever burn, nor is smoke (as opposed to vapor) ever produced, even if you connect the battery for a full minute and don't inhale on the tube at all; I tried. The vape WILL taste pretty grungy if you do this though. And therein lies the whole secret of enjoying your Launch Tube. There is a trade-off between the sweetest taste, the most dense vapor, and the amount you load. Once you figure this out, you can slightly alter your usage depending on your current needs.
What do I mean by this? Let me propose three scenarios:
(1) I am sitting at home, by myself, and I want to do four or five hits, getting the most flavor, and not caring if it takes five minutes or 30 seconds.
(2) I am in an office, by myself (or with a friend), and though I'm not likely to be interrupted, I want this to be done with as quickly as possible. There are other people in other parts of the office, and I certainly don't want them to smell anything.
(3) I am somewhere where people can see me, but I can get away for five minutes (like maybe outside to a smoking area behind the building) in private. I want four or five hits, but I can't really load and reload the Launch Tube where I'm using it.
The single "key" to understanding this is to realize that how you inhale controls the screen temperature. It's MUCH easier to regulate the screen temperature through breath control than by pulsing the battery. Once the screen reaches the temperature you like, breath control will easily keep it there. If you inhale too rapidly, the screen temperature will go down; if you inhale just right, the screen temperature will remain at whatever it was when you started inhaling; if you don't inhale at all, the screen temperature will rise, until it reaches the maximum its design permits.
(1) At home, I load a small amount enough for two big hits (what I think of as my standard load). I apply the battery for five seconds before inhaling, at which point I can clearly see the vapor starting to fill the container. I inhale for about ten seconds, drawing just hard enough that it's becoming difficult to see the vapor going into the tube. About eight seconds into the draw, I release the battery, so the final two seconds of inhaling are done without the battery connected. If I am watching the load, I'll see it turn from green to medium brown, with maybe the edges being dark brown. The very center of the load may still be a little green. For that 15 second first hit, the battery was connected for a total of 13 seconds (five second warm-up, eight second draw, two second rest). This first hit is particularly sweet tasting. For the second hit, I apply the battery for about ten to 12 seconds before starting to inhale, as I've found that the spent part of the load is acting as an insulator between the screen and the remaining fresh part of the load. This five additional seconds of preheat allows the screen to get a little hotter, and the remaining fresh part to reach the proper temperature, before I start inhaling. I inhale a little more slowly (but not much) for ten seconds, leaving the battery connected the whole time. The load is now very dark around the edges, and fully brown throughout. This second hit will not have been particularly tasty, with the "roasted popcorn" flavor typical of vapor from a load that has been smoked once or more before. Then I dump the first load and reload and repeat.
(2) This is pretty much the same as the first example, with one slight change. I load only enough to do one big hit. This is a tiny amount, just enough to cover the screen (not fill the bowl, just a thin layer on the whole screen). This gives me one great, big, sweet hit. Exhaling the tiny amount of vapor from one hit doesn't cause any smell to speak of, and the whole event takes maybe one minute. (30 seconds to take out and load the Launch Tube, 15 seconds to preheat and inhale, 15 seconds to hold my breath and put the Launch Tube away). If I want another hit 15 minutes later, I just repeat the sequence. Sometimes I use this method at home, so that every single hit is sweet.
(3) This scenario is a little different. I overload the bowl, packing it almost to the very top. This is more than twice as much as I consider a standard load for me (maybe three times as much). This is so that I can get four or five hits out of a single load, and so the load is more likely to remain in the screen with the Launch Tube in my pocket (because I packed it in). You'll want to be REALLY careful not to damage the screen if you're packing it rather than loosely filling it! You MUST support the bottom of the screen with your finger while you pack it, and you shouldn't use any pointed objects. The first hit is done as described above, but each subsequent hit requires a longer and longer preheat. The second hit requires a ten to 12 second preheat, and the third and fourth hits require a 15 second preheat. If I am in a position to stir the load between the second and third hits, that helps the third and fourth hits taste better. The ten second draw time is the same for all hits. I use this method only when necessary, and don't recommend it, because it's too easy to accidentally harm the screen, (and I really like the sweet taste part, which goes away after the first hit).
There are a few things I don't like about the Launch Tube. You can't really carry it with the bowl preloaded, my scenario #3 above not withstanding. It is the most visually unstealthy device I've ever seen. Not only does everyone notice it, they all want to come over and see what it is. This is usually not good. On the other hand it gives off no odor and is totally silent when it's used (unlike the iInhale). So it depends on whether you prefer visually stealthy or smell/sound stealthy. The Launch Tube doesn't feel nice in your hands. It looks nice. It works nice. It doesn't feel nice. This last one is probably pretty silly...
When I try out the low temp version again, I'll report back, but as I mentioned in the beginning of this message, I don't think I'll like it. This is long enough for a first message anyway. What I describe above is what works for me, and isn't necessarily the only way, or the "right" way (or even the right way for YOU). I'll be happy to answer any questions I can, and I'm looking forward to hearing your experiences. I reserve the right to be wrong about something I've said, and change my mind later once you explain things to me, or I've figured it out for myself.
Vape is good.

ps Dealing with Magic Flight has been a real pleasure. They answer their email and their answers are helpful. They send stuff when they say the will. They talk to us here and value our opinions. They have a warranty that is absurdly one sided in favor of the customer. They act like real people, not your parents. (Well, maybe that last one is a little strange).
Don't know if it's that bad in the MF, but they won't last long.
im going to buy a nice one for on the go
Wow!!
