Generally Ebay feedback system works. It does give a customer a potential idea of what we sellers are like - especially the new buyers who haven't quite made the conversion to buyin with ebay. In my opinion  I would like to see more customers come onto ebay continually and for this I think it works.

I accept that neg feedack is part of the landscape even if a seller feels slighted. I Try to turn a neg into a positve. I always apologise to the customer even if I don't agree because I am thinking of how my next buyer is going to interpret my reponse. The buyer is scared to buy from an aggressive seller.

I agree its hard but I accept it and enjoy my customers for the most part - otherwise its boring.
