What happens if the the item isn't what I say it is? Can the buyer get their money back? What if the item is perfect but the buyer claims there's something wrong with it and issues a chargeback?
The reason I don't sell electronics on eBay is because there are a crazy number of scam artists who know how to exploit the safeguards. In my last eBay sale (for all time), a guy bought my old cell phone, claimed it was broken, and then mailed me back a different broken phone of the same model. That is a difficult threat to guard against. Based on their site, I'm not convinced they've spent nearly enough time thinking about this... they are not just connecting buyers and sellers; they are going to be on the hook for any chargebacks.
