This product was ok. I probably need yo spend more time on it seems how I have only used it a few times, it has helped to relieve some of my back pain but if you stay on it too long it has the opposite effect and really starts to hurt. I would be really mindful of how much time you spend on it and make sure you keep your hand down next to you. Also do as the instructions say and start with small increments at a time.
