30 days for feedback, you can't be serious. Many items are nowadays taking this long or more. As already stated 60 days is insufficient! I do agree that sellers not being able to leave true ratings for buyers I always thought was a bad move. If a buyer (me mostly) isn't prepared for negative comments then they are deluded. I believe that if negative feedback has been left then the member should have a right to alter it later if it results in the issue being addressed!
