I have mixed feelings about this.
I avoided ebay for years, but over the past six months or so, I’ve bought a lot of stuff from EBay.
I shop ebay looking for deals. I expect that any given item/transaction could be crap, and that over time, I’m going to have some bad experiences. I manage that risk by keeping my orders small and the items cheap. With the exception of a lot of untested (and very crappy dell batteries) I don’t think I’ve spent more than $30 or so in any one order, and I don’t think I’ve spent more than $25 on a single item. As a further mitigation, I expected that when I do get crap, some percentage of the time it will be redressed by the seller, or by paypal/ebay.
So far though, I’m actually doing better than expected. There were two USB bike lights that I won bids for that never arrived. Ebay quickly found in my favor. I’ve probably spend $5 on boards I thought would have a TP4056, but instead had a knockoff. A few items weren’t quite as described, and I quickly worked out a partial refund from the sellers. I also got a USB meter that didn’t work right. The seller sent me a new one right away. I just got an order of test leads that had apparently been confused with someone else’s. The seller told me to keep them and got me a tracking number on the replacement less than 12-hours from when I reported the problem.
So, as an informed consumer, I might buy something with inflated specs because I think I know what I’ll actually get, and find that is still a good deal. Having done that, it would be crappy for me to turn around and give the seller poor feedback.
On the other hand, I really wish EBay did provide a mechanism that would allow me to share my perspective with other buyers who might be interested in the same item from the same seller. Ebay would be more useful to me if I could better trust the listings, and the ratings.
