I got the provari a few weeks ago. I tried it out but i think it is too complicated and the battery doesnt lasst very long. You can buy the the extened battery componet but that makes the thing cost like 180 bucks. In addition, my atomizers dont even work past like 4 volts. I have the silver bullet and when u have it at 3.7 volts and it can go for a couple days without changing the battery. The provari is a very high quality device dont get me wrong but my silver bullet is so much easier to use. I think I might just try and sell it. Any one else have it?? give me some opinions please!!
