Rockbirds Back Massager With Heat Deep Tissue Kneading Shiatsu Neck Massager For Lower Shoulder, Lower Back, Leg, Foot. This Massager is wonderful! I have a lot of neck and lower back pain. I am so happy to have this. It helps relieve some of the pain and the deep tissue kneading/massging with heat feels so good! It is not too hard like some of the other massagers. If you have back pain I highly recommend this!
