These have been my main issues with the lavatube...don't let these turn you off from it. It is a really nice vv tube mod and after owning the buzz and joker AV this is by far the most convenient for switching voltages on the fly. It feels great and in the hands and I would still recommend it...it does have its problems(like any Pv).
1. The button...oh the button. Its just not consistent. I would say atleast a couple times a day I go to take a hit and realize its not activated. I have also has it stick on two occasions. It wasn't a big deal...just gave it a little tap and it stopped but honestly the button is my one big gripe. When it works its awesome. It feels great and its nice a clicky. It just doesn't like to work every time.
2. The threads. If you don't have a thread lubricant I would recommend one. They are kind of rough.
3. The voltage buttons and power button rattle. You can't really notice unless you shake it but it annoys me sometimes.
4. Its long. With a 3mil tank on it it's a long pv. Still though...I have had no pocket problems with it.
That's about it. Honestly for the price of this pv those complaints are not a huge deal to me. You can nit pick just about any pv you buy and find little problems with it but when it comes down to it the lavatube is a solid vv device with an unbeatable price tag. Not the perfect pv but it will work just fine for you as a provari backup. To tell you the truth I have played with my friends provari and I prefer the lavatube.

My button doesn't stick at all. The only problem I've had with mine that you've listed is the rattling button, but that's not really a problem as I don't really shake it. lol
