I bought a Kanger ProTank after hearing so many good things about it but today my ProVari fell off my nightstand onto the carpet and the bottom threads of the tank snapped off leaving them inside my Provari's connection. This is the first time I've dropped my ProVari with this tank and I'm pretty upset that it couldn't take a 2 foot fall onto carpet. I've dropped my ProVari on CONCRETE with my ViVi Nova's many times and never have they broke. They've came apart before but never has the metal snapped in half like this tank. Anyways.. I just wanted to vent my frustration with this tank and let others who may be considering buying it know that the metal connection is cheap and will probably break the first time you drop it.
