From people that know this kind of thing (
@Ratchett ), report is a 3-d printed heater like the GH has would be extremely difficult to reproduce. I got the impression that's their ace, but that wouldn't stop shady clones from showing up on [insert internet-based marketplace] and elsewhere at some point.
My question is about the battery life. We've heard about how long it lasts and takes to charge, but how many charge cycles will a battery of this type take? If a vaporist does 500 cycles a year, how many batteries will get them through 3 years? I'd rather order all the extras with the GH, to avoid shipping cost on a single battery.
