At the risk of turning this discussion political (not my intent), please do not buy these! Please, please, pretty please.
The danger China (well, there's others, too, but the Chinese seem to be prolific counterfeiters) represents to world economies and legitimate companies is embodied in this thread: We know the product is a counterfeit; we know products/sellers like this screw a legitimate company; we know that it is a blatant attempt to cheat the consumer... but I might end up with a decent club and have more money in my pocket. It's cheap, so what can I lose?
We all lose when you do this. As long as we continue to buy goods from China because they're cheap and ignore the fact that they are counterfeit, the deeper this problem will become. Go buy a legitimate clone -- they're not pretending to be something that they aren't. You'll still get them cheaper, but you'll know what you have and you won't be feeding the scammers.
