FastTech is great. Just read their forums. There are issues, but they do their best to gain customer satisfaction. I've bought a lot of stuff from them and will continue. How else would I afford mods and RBA's? So far, I've ordered a K100-101, several vivi nova tanks, an Innokin SVD for cheap. About 6 or 7 RBA's that are small, and cute. Several of the Cobra RBA's. I'm ordering a Vamo V3 and another k101, some oddys, more protanks, and evods. The price and service are wonderful as is the free shipping. And it's quick too. Not next day quick, but less than 2 weeks. So that is enough good for me. For any item that you order, check out the review and forum info for it. Everyone on their forum is honest and they don't pull punches. The people that work for FT that are on the forum are good and answer questions and try to get info that is needed. Super site. I've never ordered from anyone else, but they do tell you if it's a clone or authentic. I'm also going to get the Grand Vapor Private V2 Mech Mod for $12. The info in the forum says it's aluminum threading to get an adapter so the threads don't get ruined. But for the price, I'll do just that.
