Hey, I'm very brand new to vaping. I am not technically a virgin but I might as well be after only trying the blu disposables until I get my 510 RIVA Special Edition Kit. I ordered the Riva 510 because of the great reviews but then I noticed right after I purchased the kit that some people have a lot of trouble with the batteries. Are there any good back up batteries that work with the 510 RIVA that may not necessarily be the ones especially made for them? Perhaps another brand is better? Not saying all 510 RIVA SE batteries are crap but I've been reading quite a bit about them. So now I'm concerned. Especially being that I'm new and I'm going to try to kick my relapse into smoking seriously, I want to make sure I can vape.
