the MVP is a solid piece of kit, feels great in the hand, and it is all contained. No chargers and batteries to contend with. It also has a socket in it to allow you to charge other items, such as if you dare take your iphone off charge for more than an hour!
I think its fair to say, i have a lot of vape gear, but as i sit here writing this, i have my MVP next to me
it works, it lasts, its solid, and you can get away with walking about with it outside
