I originally bought this product for my husband to aid him in recovering from a back injury, and upon trying it myself I decided we needed to get a second one since I wanted to be able to use it for other benefits and he often travels for work taking the belt with him.
Have only been using the pro for a short while but I do like the added vibration feature. I had the basic one and used it for a couple months. I'm glad I upgraded. We'll see if I get better results.
