I have not tried it yet, but I’ve used this same brand and model at my physical therapy. Once I found out how many things I could use it for, I decided to get one for myself. I’m recovering from spinal cord surgery so for now it’s for my lymphatic system/reducing edema. Though I look forward to using it to regain all muscle/strength I have lost. I will gladly give an updated review once I’ve had a chance to use it. So my rating is based on using it at PT, if I got what I expected (which I did and more..the exercise guide plus the internet extras), and the quality of the product upon unboxing.
