I just sold my crafty for a mighty so i guess i'm joining this group now.. yo.
here's my quick review from someone with experience with both units.
Mighty > Crafty :
+ longer battery life (double crafty)
+ screen with controls on device
+ can run on essentially 0% battery through charger, crafty uses
mini USB charging which is slower
+ heats up faster imo
+ slightly less drag imo (this might not be factual, just what i found from my use of both vapes)
+ can screw cooling unit on either way, no way of screwing it up hehe
- bigger than the crafty and is not really that portable or discrete, crafty you could easily hide, mighty is pretty friggin obvious, like you pull it out and anyone who has any idea what a vape is can tell immediately what it is. So if your looking for discreteness and only imagine your probably going to have a max of 3 (5-10mins) seshes in a day + you carry a Iphone 4S upwards or appropriate android phone around with you, then the crafty is for you!
- Extra minus is that I actually think for people concerned about getting the 'most control' out of their vaporizer, the crafty actually offers MORE control through their app than the mighty's basic digital screen.
If your going to go high end and dont care as much about discreteness I think it's definitely worth spending the little bit extra to get the mighty.
Also a lot of people complaining about the 1minute shut-off, I never really found it to be an issue, this thing heats up again really fast anyways and since it has such short battery life i'm happy with it shutting off if i leave it for 1 minute, I can totally see Storz and Bickel's logic.
