For example, the provari is probably one of the best mods, a little bit bulky for my taste. But what i really don't like is the price tag, but if i lose that thing... oh well.
Ahh, but a ProVari will last and last and last, while the chinese battery holders will die and need to be replaced. The Provape is having a sale on their chromes, $40 off. They discontinued them because of some problems with etching their logo.
You will recoup the cost. And so, that is what I bit the bullet and just bought.
