I like the ease of use of this #TensUnit010! If you are going to sit in a chair and use this unit, you will like it. If you are going to clip it to your belt and walk around, be ready for an unexpected jolt from hell if you bump the rollers.
My husband’s shoulder pain is helped by the device. While my aches and pains are not muscle, but due to osteoporosis, I don’t get as much benefit, but the massage setting on my lower back sure feels good. Like having a tiny little Swedish masseuse.
