I don't dislike
fasttech. They're a discount/clone seller. I don't want to wait the several weeks for shipping from China and risk any problems with customs (batteries) or whatnot. So I just by from regular USA vendors since I'm in the USA.
Fasttech is what it is. If you buy from them and know what they are selling, like FranC said, what's the problem?
I think you have to know what you are doing/getting, that's all. I'd just by from USA vendors because I'd have it in 4 days and support the local vendor. But like I said above, the USA reseller is "stuck" in a "price-fixed" situation. This is why clones are so popular, I'd guess. And why Fasttech has a niche.
Manufacturers should just sell a unit at X price-per-quantity (so discounts apply to bulk purchases) to everyone. The reseller can decide on the profit margin. That's the other problem though, it means that Walmart always has lowest prices for what it sells because it buys in the largest quantities whereas Joe-Shmo's corner shop can't afford to stay in business.
