People buy from Ebay rather than authorised dealers because its cheaper and everyone likes cheaper, why else would you?
If even Cobra cant tell if one of their clubs is a fake or not then the counterfeiters are doing a good job and perhaps suggests when buying Cobra or other brand you are in fact just paying for a name, for me there are usually subtle giveaways on fakes but it can be hard to tell, you get a sixth sense on it.
Real question is if you are playing Pongs instead of Pings, if the shot results are as good, does it really matter? Brands is all a vanity/psychological thing that we all fall for i.e if a putter has Scotty Cameron written on it I will hole more putts! - then when you don't you blame it on all kinds of things but not the putter!
