It's hard not to like a Provari. If it's in your fist, the fire button is conveniently located. The satin finish is smooth and looks like quality. The atomizer threads on mine are still nice and smooth and tight after almost two years. If it has an issue it will probably be that you occasionally find yourself in menu mode when you expected to vape. Switch bounce causes that and few manufactures have designed in the simple R/C network that would capture the spikes from the button press. After a while, you discover that a straight on button press will minimize that.
Overall, it's a great mod.
after I set something, I've forgotten to wait a second and let it STAY SET,,,,,,,and I've accidentally turned up my voltage (coughgagsputter),,,,,,,,or I get a code 23 (whatever that is) and it doesn't fire,,,,,,
but again, that's ME,,,,,the menu is easy to understand though,,I just have to learn to wait a second after setting something.
