If you want to know whether these are good for racquet ball, this is not the review for you! I bought these balls because they are the perfect size to use for trigger point massage for those knots that you get in your back (maybe from playing Racquet ball). These are great! And there are three of them, so that when my granddaughter makes off with one, I do not have to start hunting all over the house.
