It works really well when it is fully charged, my one gripe is that the battery does not last long at all. It might get you through a short session while on the road but ideally It should be kept near the charging port. I almost considered sending it back but decided that it was still very cool and novel. I have had if for a week now and have ripped it almost everyday. I like to hit wax first on one of the cooler settings and then bring it up to burn off the rest. I am not a very experienced wax smoker and I really like the throatyness of a strong rip. This this is pretty sick. Would love to see the newer gens have less water for diffusion and more battery for longevity.
