My wife is 61. She was diagnosed with rheumatoid arthritis when she was 42. It affects her joints and organs. Her arms and legs and feet and toes are twisted. This massager comforts her. She likes the vibrating massager and the heat. She can't handle the kneading spinning ball massagers, she is fragile and they hurt her. She likes this one a lot. She uses it with a full body massager while I sit by her and massage her hands. Buy it. It's a small price to pay for some pain relief.
