I've had my Provari with the original finish for about a month now and use it often (EVERYDAY) there is no sign or wear & tear at all on it the finish is still like the day I received it. I have to say it is the nicest tube Mod I have ever owned, it is so dam easy to adjust and dial in the perfect vape whether using just a regular Atty, a tank, a Maptank whatever it may be. I use it most with a vapemate + Mini 2ohm 801 @ 4.2V and the flavor and vapor with this set up is awesome, also just dripping with a reg ohm 2.3 510 Atty @ 4.6 is awesome too. For those waiting still on delivery of this unit I have to say its worth the wait, it's the Bomb.!!!
