As far as battery safety goes look at all the cheap fake batteries which are sold at bargain prices with the wrong specs on them. The Provari won't fire them and that is a feature and benefit to the Provari owner. You own expensive mods and I'm sure you use high quality batteries, but for the $25.00 mod owners are they going to buy $12.00 high quality batteries or cheap $6.00 batteries? Unfortunately the $25.00 mod will fire the cheap battery.

This is a good point for the liability of the manufacture and distribution of the device. But how many reports are we seeing of regulated mods venting? I've not seen any, but if someone has links to some I'd be interested in reading them. I understand the risk is way higher with mechanicals and why.
