This is amazing. I have lower back pain so I thought I would give this a try. Its great at helping with the pain. It helped relax the area that is usually in pain. The heat is a great addition and the fact that you dont need any lotions or oils it a great plus. If you have issues with deep muscle pain or just want a nice massage without goin anywhere give this a shot.
Output:
positive
