I will admit I am quite surprised that eBay still exist at all.
Last time I used their website, it was over complicated, non-responsive, and I got scammed, and it was more of a pain in the ass to deal with eBay as you needed some Master in eBay Scam Protection, and if you missed one of the 50 golden rules, you would see your money gone with no help from eBay and the 3rd party seller, in another country, laugh his/her/their ass off.
That why people moved to site like Amazon, where even if it not always the case, the customer has a feeling of liability of the name. While there is horror story on both side, I never had problem getting a refund for a defective product, or the like with Amazon, cheap or free return, etc. The whole eBay model got shifted and phased out by the Platform like Amazon, AliExpress, etc,etc...
Doesn't seem like a smart move to buy a sinking ship, but hey, good luck with that !
