<human>: EDIT 2: [Problem resolved.]

Original Post:

When the buyer messaged me, he said that he did not drop the iPod or anything; it simply stopped working after the battery drained and now it won't charge up. He said he has tried multiple USB sync cables, computers, and wall chargers and none of them has gotten the iPod to start up. He has a 100% positive feedback from both selling and buying for 3 years, so I am leaning towards the fact that he is being honest and is not trying to return something that was dropped into the Grand Canyon and then circumnavigated the world.

The buyer does not seem to be very technologically-inclined, so there is a chance that once I receive it, I may be able to unbrick it or something along those lines.

From searching around, it looks like most eBay disputes (should I decide to fight his claim) end up getting resolved in favor of the buyer. A lot of sellers on the official eBay forums seem to vent about how the eBay dispute system is worthless and protects the buyer more than the seller. On top of this, should eBay rule in favor of me, the buyer could then call up his credit card company and ask for a chargeback, which would be another fight in and of itself.

Reddit, if you were in my shoes, what would you do? Would you take it back and hope for the best (i.e. I can easily fix it by DFU/Restore/etc) and that it is not a return fraud situation? Or, since it broke in the buyer's possession, would you fight it with eBay and see what happens?

<bot>: I sold an iPod on eBay. Guy leaves A++ feedback. 2 weeks later, ipod is broken and the guy wants a refund. eBay likes to troll and sides with buyers more, so should I cave and give a refund?
