I actually have a FIreFly 2+ I broke it out last night to give it another shot and seemed to get some good production with it. But the irritating factor is needing to stir and the lid design make it really unusable as a portable solution for on the go. One day a device will be made that has great airflow, no need to stir, on demand, will use optional dosing capsules ( for on the move simplicity ) large removable batteries and will be built strong enough to handle drops. :-)
Oh yeah, I never used that one but I used to have the original and my brother had the FF2, they are fun and nice, however yeah the stirring and the cleaning was a bit tedious, and the long-term reliability... With glass stem-based pure convection, I love how the chamber and vapor path are fully removable and cleanable and replaceable! Very easy to load and unload with them, almost like capsules themselves, but yeah they allow the use of capsules too! Also with the regulation and my technique with TetraP80 and Tinymight for example I never stir, as long as you don't load too much there really isn't an issue at all in my experience, great extraction very easy to use, plus the easy replaceable long-lasting batteries! So yeah what you are describing is absolutely the TM, plus it's got the temp control dial for a full range of power settings, although yeah durability is the last risky point... In my opinion it's worthwhile, as someone who's pretty careful with their things, particularly for all the benefits I listed, however I will also say that I did drop my first TM sitting on the couch on to hard wood floor, slipped out of my hands and fell bottom down fortunately, so it was protected enough that none of the internal glass or ceramic pins broke, the only thing that happened is that the battery contact got slightly pressed down so now I just have to always screw the lid down all the way flat with that one, which is not a big deal and the best thing to do anyway (my new one does not go down all the way flat, but I do always screw it all the way down now to be safe too, because I used to only tighten it down partway on my original one when it dropped so that is also likely the cause of the battery contact getting compacted anyway just saying lol)
