I bought this after my leg was in a cast for a month. My physical therapist uses one like this but a different brand. Healing is not an overnight thing. I’ve been using it for two days and I believe it’s helping along with PT.
Lots of massages to use. It has a timer with 10-60 minutes on it. And it has two sets of plugs to use, A & B. It’s rechargeable and the charge lasts a long time. I needed to charge it before I could use it. I love that I don’t have to depend on batteries!
