i agree with operator. the whole point of the feedback idea is to encourage professional business practices by holding people accountable for what they do, but more importantly how they handle disputes. you are not supposed to leave feedback until he has handled the situation. if he has good customer service and accomodates your concern (refund, partial refund, exchange, etc.), then he gets a positive. if he is responsive but doesn't give adequate accomodation, maybe a nuetral is in order. if he tells you to f off, or you email him for several weeks without a response, then he gets negative. there's a whole article about it in the "feedback forum" on ebay, possibly even shorter than this post.
