Have you looked at the e-power brand of e-cigs? The price is similar, but it's a component system that uses 14650 batteries. no more buying expensive ego batts when they die. I would give you a link, but I'm new. I know gotvapes.com sells them and they are a listed vendor. but I don't know if I'm supposed to be plugging them or if it's against the rules.
I looked at the e-power also, but then I saw on vendor selling replacement bodies and it made my think that they were made cheaply if people were have to buy bodies to hold the batts in...
I really prefer the types that take regular (protected) batts (less to carry around with you and cheaper in the long run), but the couple that I did see that did that and looked like a high quality product - were also very highly priced... I wish I could see some of these in person instead of relying on just pics to make my decisions...
It must not be against the rules to plug a vendor since I see it all the time...
