Really not sure what vape to get. I've been using a sticky brick and a vapcap for the last month and a half. I want an electronic device. Crafty, mighty or IQ? I'm only asking here because all the reviews I can find on crafty are of old units with the weaker batteries. If the battery is good enough for a solo heavy user I'll go crafty.
It's not just battery charge that separates Mighty from Crafty. For example, because Mighty has two batteries, they don't have to work as hard as the single battery in Crafty. I think they will have a longer life overall, i.e., more than double.
Mighty is also now shipping with the 'new/improved' batteries.
The unit (including batts) does not get as hot during use, meaning it is not stressed as much. My Crafty used to overheat and shut down regularly. When it cooled off it could be used again. Mighty has only done that once in 3 years' use.
Crafty charges via usb at a slower rate than Mighty, so, when depleted, Mighty will charge to full faster than Crafty. Mighty can also be used during charging (plugged in) and Crafty can not; at times you just have to wait for it.
I also prefer Mighty's on-board controls to needing a separate device and app.
I think that if you plan to go to higher temp range, or use a water tool, or both, you should not hesitate to choose Mighty over Crafty.
As I've mentioned many times, I went through 4 Crafty's before upgrading to Mighty and I realize now that this is the unit I should have started with.
