Hello, please note that you cannot write the seller's name here, because it is against the rules. The administrator will probably delete or modify your post if you disclose that information.
As for feedback, there is 2 things: everyone can read the feedback you left for others except for the star ratings. Out of 53 feedbacks you left, 5 were neutral and 3 were negatives. That is a combined count of 15%. You have to admit that it is a pretty high average...
As for the stars, yes, the seller you left them to can find a way to know what you left him. However, the other sellers can't see that, unless the first seller write to others and advise them.
By the way, on eBay, anything less than 5 stars is a nightmare for sellers, especially part time or small sellers as myself. If the average count goes below 4.6, they end up paying more fees, see their sales restricted, loose the Top Rated badge, etc. If you are not satisfied 100%, but don't want to hurt the seller, the best way is not to rate the stars (yes, you can do that).
