Twice I've been burned on eBay buying fake KMC chains. Both times I managed to return them after reporting the issue to eBay. The 'Bay did NOTHING to the vendors, as the same items were still up for bids afterwards.

The pics on the items were of real KMC chains, the products were fake. Caveat emptor & Si nimium bonum est verum esse, verisimile non est verum !
