Comparisons with the Firefly as requested by Hodor.
First off they are so different it's really apples and oranges:
1) Firefly is pure convection, while the Crafty is a combination of conduction and convection. In practical terms that means that whatever you put in the bowl of a Crafty, for best flavor and result should be finished off. With the Firefly you can easier just take a hit once in awhile and the herb stays tastier as there is no slow conductive residual "baking" going on.
2) With the Crafty there is little to no learning curve, making it easy to pass around at a party or concert. Also absolutely no stirring required and the ABV is always very evenly done.
3) When needed, the Crafty can be much more stealthy and get the job done fast.
You can take a couple of huge draws easily and effortlessly.
While the Firefly has much less resistance then for instance the Pax, the Crafty has basically zero draw resistance which is rather nice actually.
4) The Firefly is to me more like a personal instrument that needs to be handled skillfully and patiently: sometimes the hits are perhaps too whispy,
then when you want clouds and you hold the button too long black charred specks in the ABV. The beauty of the Crafty is the EXACT temperature controls.
5) Batteries: I can't tell you how happy I am to see both on the app as well as with blinking indicator lights how much juice there is in the battery. So much disappointment when firing up the Firefly and the battery gives out. And yes I have an extra battery and all of that. Also the batteries of the Firefly start draining immediately when not in use so that even that extra battery may not be as charged up as you thought and there is no way of knowing.
6) Still on the battery aspect as both my Firefly batteries stopped working completely in less then two months (they were replaced free of charge)
I think a major design flaw of the Firefly is having a potent heater right next and almost in touch with the battery. The battery on the Crafty is completely separate from the heater, giving it a better chance of lasting longer.
Besides the fact that it is a pain in the butt to keep replacing batteries it's also quite wasteful environmentally to throw that many out.
7) Aesthetically speaking the Firefly is way prettier with the glass bowl and stainless steel vapour path.
That said, the cooling unit in the Crafty works way better and even huge draws never feel hot.
Also with the Firefly you sometimes inhale little pieces of material, which does concern me. This never happens with the more intricate design of the cooling chamber on the Crafty.
I could make another seven points but I'm getting tired LOL
Hope this helps...
