It's probably best to list how this affects us in the actual ad or as a message when a buyer is paying etc

this is what I will put  from now on.

eg. "When giving star ratings for my item in "Positive Feedback" Please know that 1,2 & 3 are Negatives and only 4 & 5 are Positives. If you feel that I only deserve a 1,2 or 3 please message me first and I will try my very best to resolve what ever the issue is. If you got the item as described please rate it as 5 stars. Thankyou for shopping with Not Just Stagea Parts."
