My local tobacco store was selling Vapor-x kits for $22. I bought one cause i'm a noob. It definitely will not accept any other 510 or EGO threaded device. Despite that, it worked ok and the battery lasted really well for a 650mah, using it however is like trying to suck a brick through a straw.
Online the same kit I bought is sold for $80?? Total rip off and waste of money. That's what I get for being impatient waiting for my Kanger EVOD kit to arrive in the mail!
