Bugger. Those look bad.

Perhaps you might be better buying them through AliExpress. That way, you don't release the funds unless you are happy with the delivered goods. I've not had to use that system in anger but it may be better than the ebay system. That seems to be how they allay fears when buying from unknown buyers in China - otherwise most buyers would be very reluctant to even think of buying through them.

My understanding of ebay is that they almost always side with the purchaser, so you would be very likely to get your money back. For that, you would probably have to reject his "offer". And in the US, I assume the credit card company is also liable for bum purchases? That sounds like the backup plan if ebay don't play ball.
