I've had mine for close to a month.
The battery life is long, I'd say 4 hours easily of HEAVY
vaping. I've had it last me all day long at work. The batteries are also affordable!
Atomizer life really depends on you. I've heard the Janty Classic Kissbox atomizers (the one that it comes with) are fairly sturdy. One of mine is dead, but that could have been a newbie mistake. Either way, the warranty is good, just take care of them so Ethan doesn't have to swap em out so often
My only other PV is a Janty Mini Fogger, which is really no good comparison to the JS. The Mini Fogger has warmer vapor, but much less. The cart capacity is like comparing pennies to silver dollars. Battery life doesnt even come close. 90 minutes or two hours on the Mini Fogger.
Really, I dont think there is anything about the JS that I would want to change.
I'd say go out and buy one, but I really don't know what you're looking for in a PV. This has it all, but it's different from the others.
