I still don't think you were burned. First off you do have the option of returning them. But further more you paid $20 for two chargers. If only one worked it cost you $20 for one working charger. Which still is an average price for a battery charger.
I have pulled the short straw a few times when trying to get an item on eBay. Whether it was to cheap out or I was impatient and didn't want to wait for retailers to get additional stock of an item. Most recently was a 32GB micro SD card I picked up off of eBay for $50. I knew it was coming from Hong Kong so I didn't put too much faith in it working. Fortunately for my sake it did work, but I hoped for the best and expected the worst so I didn't feel like I got burned. When purchasing a knock off from eBay you have to have that attitude.
As you said eBay is a very buyer beware site. But in this particular situation I think you still made out well regardless of the initial charger not working. Unless the auction was for a Verizon OEM charger. If the seller was advertising an OEM product and sent you a knock off, then you have every right to complain.
Good luck!
Well, first the 2 chargers cost me less then 10.00 shipping included and they were advertised as Motorola Chargers. The only thing Motorola about them was a very well placed sticker that said for A855.
Now if I get ripped off on this guy I'm buying from Brooklyn then it's another story. We will see.
