Dr. Franklyn's Compact Hammer Massager

This is one heavy duty massager! I have several kinds of electrical 'roller' massagers such as chair pads, shiatsu neck massager, as well as one for feet. Those are okay, but this percussion one is great. I can use it only on the low setting and over my clothing because it gives a good 'beating'! But the after benefits are worth it; it really helps alleviate my tension and tightened back muscles. Everyone in the house loves using it. I was afraid that my arm would tire holding it for several minutes, but it really doesn't. The percussion part is very smooth and glides easily over clothing. I can't how it does on bare skin since I haven't used it in that manner. This is a fantastic buy $20 and less expensive than all of the other massagers I've bought. I do hope it lasts a long time.
