its a pain in the .... to have to go to multiple places for atomizers, batteries etc. liberty flights carries the riva bateries, sells them for 12 bucks . they are 3.7volts, not 3.2 volts like a lot of the others. i've tried box mods, i've tried different batteries, and these are the best bang for the buck, at 12 bucks if it goes bad, you can throw it out. much more economical then the replacable battery solution. you can get 3 riva batteries or more for the same price and you don't have to worry about a switch going bad that costs the same as a battery. plus they are 3.7 volts and that makes a huge difference between throwing a cartomizer out or being able to use it another couple of weeks. anyway, just one persons opinion, but it sure would make it easier for me to get free shipping if I could order batteries as well. box mods crack, they break, they big, etc. I think i've gone on enough
