My limited experience with Fastech. A couple months ago I ordered a K100 kit for around $35. It included the K100 body, a battery, a charger, and I think a cartomizer also. I had read all the stuff about Fasttech on here and knew I was in for a wait, and I was okay with that since I have a good setup already, and just wanted to try a mechanical for cheap. 3 weeks later, the shipment was returned to Fasttech and they issued me a refund. I'm guessing it got returned because of the battery, and really I was kinda glad, because while I was waiting, I read alot about batteries and chargers and wasn't comfortable about the ones that came with the kit anyways. Since then, I bought a K100, battery, and nitecore charger locally, and paid a bit more.
I will probally order from Fasttech again, but it will be for stuff I want, and don't need, since anything I might need I can get at the several shops I have in my area, or online here in the states and have to wait at most, 4 days for. I definitly will not be ordering any batteries or anything with batteries from Fasttech again because it seems all that is gonna do is tie up money for a month, and I won't be getting anything.
