I have my feedback set to auto because I couldn't be bothered doing it manually (leaving feedback that is). If I was just selling a few things a month I would wait until the customer confirmed everything was OK. Sometimes I wish I never left the feedback first when I got negged. I don't really understand why a buyer wants feedback anyway.

The rating system ebay has is very poorly informed. Is it like 5 stars for a movie? if so I would very rarely rate someone 5 stars.
