I have them both i use the crafty for sessions with friends and the grasshopper for 1 hits.
The flavour is better with the grasshopper but much much much cooler on the crafty, battery life cant rly compare the uses are different and the crafty doesnt have a user exchangeable battery. What...
I kinda wish they made another model called the dung beetle, which is larger with a bigger cooling unit and more space to adress other small problems.
Because this heater is something else most convection devices require stirring even the firefly 2, this one seems to even vape no matter how...
Got my unit today but i have to say it gets rly hot rly fast i wonder if its supposed to...
Edit.
So hot as i take my first draw the second one can be with the device off, vapes evenly tho.
