Re  :  no idea why it was left, it was from a repeat buyer who bought several things, left identical, pos FB for everything and that was the only one with a low DSR - for description,

I'll try & keep this brief and hope these comments are not repeated on another thread.  

Back when I was a newbie Buyer on Ebay I accidentally left 3 Stars a couple of times for Sellers & of course could't find a way to correct it, but figured 3 Stars was Neutral so shouldn't have a neg affect.  As soon as I read about this new Defective System, I contacted CS and contacted them again in the last few days suggesting there now needs to be a prompt, red flag or something querying a Buyer before they leave any 3's under this new system.  A prompt for only 1's and 2's is no longer acceptable.

First response was ' I understand what you're saying.  Good idea.  We'll pass that on to the technical department" - no response to the latest message.  I guess time will tell, by which time who knows how many defects we may have received unjustly.
