The Knobble II Massager by the Pressure Positive Company
The Knobble II is probably the most surprising on my list. The size of a doorknob, this little massager does great things. The smoothly rounded tip applies pressure to trigger points in your back, relieving pressure and tension. And the soft band of Santoprene, a non-latex rubber, around the base helps with friction techniques used by therapists. Using your own body weight and your hand, you can get an effective massage similar to the kind you would get by the hands of masseuse. Made of durable polymer, this massager never has down time. No parts to fix, no fuss, and easily stored.
