I've been using Puresmoker products since day one. Currently I'm using a Legacy Mini with extension tube and Kick. It's great. The small size (18490) is nice and the craftsmanship is outstanding. But it's finicky. The Kick has to be seated just right and all the contact points have to be squeaky clean or it misfires. This leads to more futzing around with it than I want to do. So, I ordered a Provari Mini with the extension so I can use my 18490 bats. At the very least I'm hoping that having both will enable me to take the Legacy out of service while I disassemble and trouble shoot it. At most I'd be happy if it's more reliable than the Legacy. I love Puresmoker, but their decision to rely on the Kick for VV (VW, actually) seems like a mistake to me.
