It seems like everyone has their opinion about fastech and you are entitled to yours but I'm quite happy with the batteries and chargers I've gotten from them .
If you were able to correctly identify exactly which batteries you were looking for, FastTech was a good place to purchase batteries. The problem I had with FastTech is that they were selling
un-protected Li Ion batteries along with protected Li Ions, IMR's, and the new hybrids. Some novice who would go there and not know what they were looking at could easily order a dangerous battery not fit to be used in a mod and not know it. I've seen it myself and there was a long thread about this situation just a couple of weeks ago.
I read just this week that because of new shipping regulations, that FastTech will no longer be shipping batteries overseas to the US. I've not confirmed this myself and don't really care because I personally would not buy from them, preferring to support a US-based vendor who sells only mod-safe batteries and chargers. RTD Vapor.
