To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I read all the reviews for this, and I wish I had paid better attention to them. They fit really well on the rings, however there is nothing to keep them in place, and eventually they fall off. The one that I had on my ring fell off, and one of my grandkids found it and tried to put it in her mouth, which could be a choking hazard. So I'm headed to a jeweler to get it fixed the proper way instead.
