Get another Mighty; I will list several reason I think you'll be better off with a Mighty
1.Based on the number of complaints in here the Crafty is less reliable.
2.You don't need a smart phone or computer to adjust the settings on the Mighty.
3.You won't have to worry about charging the Mighty every half hour.
4.The Mighty heats up faster than the Crafty because of the extra battery power.
5.The Mighty charges faster because it has a 12 volt charger; the charger for the Crafty is 5 volts.
6. You won't need spare parts for two different vaporizers.
I don't know if most people realize that the Crafty was an afterthought. Storz & Bickel designed the Mighty, and then decided it might be nice to have a smaller version of the Mighty.

6. What is the difference between the CRAFTY and the MIGHTY?
In general, you can imagine the CRAFTY as the MIGHTY’s little brother. When designing the MIGHTY, we thought it might be nice to have a smaller version, too. So we used only one lithium-ion battery instead of two for the CRAFTY and we also dispensed with the display of the MIGHTY to make things smaller. The CRAFTY has only one button to operate it and one LED-light to give the user coded information regarding charging, heating up, temperatures and potential errors.
Then we thought, hey, nearly everybody carries a display around with him/her – a smartphone. So we added a Bluetooth Low Energy chip to the CRAFTY and made an App, which provides even more information than the display of the MIGHTY. However, to operate the CRAFTY, no smartphone or App is necessary. It works very well with the default settings, eg. Basic Temp. 356°F (180°C) and Booster Temp. 383°F (195°C) which can be set individually with the CRAFTY-App.
The MIGHTY has a slightly more powerful heating (30 Watts heating performance compared to 27 Watts with the CRAFTY, double voltage and capacity because of two batteries) and a slightly better cooling (because of the bigger Cooling Unit). By testing them blindly, you won’t realize a difference in vapor quality. Another difference is the price: The CRAFTY costs USD 399,-, the MIGHTY costs USD 469,- including free shipping. (Everyone knows that Storz & Bickel dropped the price of both units since they wrote this on their website.)
What both have in common, is the full convection air heating combined with additional conduction heating of the Filling Chamber walls to give the user powerful vapor draws from the start. A good heating always requires an efficient cooling, otherwise the taste will be awful.
