If you don't feel comfortable. I have bought lots of stuff from vape101 and always had good experiences with reasonable pricing. Anyway hope it helps.
From those threads and the things they led me to, it sounds like they're a bit on the sketchy side but some people have had no problems. Thanks for the info.
