This is a great find for me because when I buy from someone on eBay I like to see what their Negative or Neutral feedback was about. And when the seller has a high feedback its time wasting to sort through it all. Naturally, if it's like mine, if its people complaining that their package wasn't delivered in 2 days to Europe from Hawaii or has a -2 rating I would disregard it.

Just type in the seller ( or buyer ) and it'll get all that info for you.
