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.
This product was recommended to me by an ophthalmologist when I had a chalazion cyst that was causing pain and headaches. Very easy to use, comfortable, relaxing, and helped with swelling and irritation before and after the cyst was removed. Nice cloth case, too.
Product broke after 2 uses. I heated for 30 sec as there were no instructions. Fabric fell apart and beads fell all over the place. Bought a replacement for 1/4 the price and use it daily. This is a Poor quality product
