Works well, despite being unexpected!
I have no issues with the massage ball I was sent or with the seller, it was packaged well and arrived in good condition. I’ve used it and it works as described, I found it particularly useful for hamstring/glute myofascial release. My issue is that I originally placed an order for a completely different massage ball that  was smaller and made of a different material and had a different seller than this one. It that had a delayed shipping date but I placed the order and was expecting that product but without my knowledge Amazon changed my order to this product. I decided to keep it because I was in need of a larger massage ball anyway and this one serves its purpose well but I will place a new order for the other item and hope for the best.
