I've never had any issues with Ebay and have bought over 200 items from around the world from their sites..... ( touch wood )
I've been on and off ebay for well over a decade or more. It is great for buyers if you are careful, terrible for small sellers. Their fees are outrageous now and the 'seller protection' is anything but. They will 99.998% always side with the buyer in all disputes. It doesn't matter if you have tracking results, pictures or items, pictures of packaging, signatures, drone flyovers watching the guy out by the UPS truck, etc., ebay will eventually just decide "what the hell, let's just refund 100% to the buyer just so we look good." There has bee a few times I lost the item AND the money, thanks to the Ebay/Paypal setup.
