Just an update on this, he ended up leaving negative feedback yesterday, changing his story for the 3rd time. In the feedback he said that the item "was not first quality and bad customer service," or something like that. The person can barely speak English - which probably explains how he missed the 3 reminders in my auction to check the measurements. I called eBay, they review the messages between us and the lady says that she can clearly see that the person was lying about the quality issue, because his original claim was that it didn't fit, and his first change of story was when he opened the case and claimed that I misrepresented the item. The lady from eBay goes on and on about how I'm right and he's wrong and how she also runs an eBay business so she understands, but basically says there's nothing they can do. And of course, I can't leave him negative feedback, so there's nothing to warn future sellers about his buyer's dishonesty. What a joke.
