I bought this to replace smoking entirely and I've done that for about 2 months now so far. I vape a lot.
Temperatures that seem to work best for me are 385 to start and 420 around 160s left. Sometimes I do a full round at 385 then switch it up. I generally end up charging the vape like twice a day, but it charges extremely fast and I don't like it to go too low.
The only two gripes I have are the led being too dark in direct sun (I just cup it with my hand and it's fine), and the bowl size being a smidge too small which is also fine because you conserve so much with this guy.
