Happened to me once. Purchased a set of Taylor Made irons on EBay. I had them almost two months and the head on the 7 iron snapped like a twig. I contacted Taylor Made to make a claim only to find out they were knock offs. Attempted to contact the seller on eBay only to find out they didn’t exist. eBay Couldn't help me out because I had gone past the time frame. This happens quite a few years ago. This happened quite a few years ago so chalk it up to a very expensive lesson learned. Buyer beware.
