Bsse unit Lavatube is $70 at Volcano, base unit Provari is $159 at Provape, so for kicks & giggles lets just call the Provari twice as much, not 4 times as much, you need charger & Batts for each. I will still take my Provari over the Lava anyday of the week. And yes any unit can fail, as far as customer service goes Provape is one of the best out there, and even out of Warranty Dave at Provape is super fair to fix a unit. I would like to see what people are going to do when there Lava tube breaks once Warranty is up as well, Provari is a much more solid unit by far then LavaTube, plus if something happens to my Provari I know 2yrs down the road I can send it to Provape and have it back in about a week and like new again. Nothing against the Lavatube though its a great " CHEAP" VV unit, but you get what you pay for with anything. Fit, finish, USA made, Provari wins in my book. No trolling, just my personal opinion, where all welcome to those.
