Ebay is like a superstore for counterfeit items. Most of the problem is from sellers from Hong Kong and China. I've never purchased anything from HK or China that was of acceptable quality. I deal with a lot of people (some here, a lot more via email) struggling to troubleshoot strange problems and in virtually every instance where they purchased parts from ebay, those parts were the problem. It's like NTE parts. If you want to avoid problems, Don't use them. Always buy from reputable distributors.
