Hi all,
I purchased an ASIC Block Erupter cube back in January off ebay. It came shipped 2-day USPS Priority. No damage at all. Worked great. Time to sell it (too much noise, too much heat, too much girlfriend complaining, etc).

Sold on ebay. Shipped in same box it came in. Even added some extra air-bubble packaging. Got USPS insurance for my original purchase price because if it gets damaged, then I'm out the hardware and the refund to my buyer.

Sure enough, none of the cards work when buyer receives. Submitted insurance claim. Buyer takes cube to local USPS for inspection. 20 days later, claim denied because "no external physical damage evident."  I have one more appeal.

Just because a car has no external damage doesn't mean the engine block is locked up right? I can't exactly explain to a USPS employee how to turn it on, configure it and see all the X's mean it's broken.

Does anyone have experience with this? What can I possibly write in my appeal letter that will explain to them how this is damaged beyond repair?

Thanks!
