I believe the rating system should be reviewed. I think it should be mandatory for a buyer to provide a reason why the rating, even if it’s 5 starts. If the rating is low because the buyer had a bad experience or any other reason, the Author should be given the opportunity to fix whatever is broken, or reach an agreement before the rating becomes effective.
Right now buyers are rating items down and we don’t even have a clue why. How can we improve our items or try to help the buyers if we don’t know what’s going on.
