Nice alternative

I have 2 of these massage scooters purchased at in order to work with both hands simultaneously and am satisfied with the decision. They fit comfortably in your hand and I take the opportunity of small filling opening for massage oil & Co. The stone ball I previously heat on the radiator (or warm water in a bowl) before before I take this.

I deducted a star because the ball is not as shown on the image protrudes far, only a few millimeters above is, therefore, there are quite frequently with the plastic part (which is rounded down to luck) contact with the skin. Interior is also unfortunately no sliding seal etc. mounted between ball and bracket, whereby the ball rubs against the plastic and now and then a noise that are at a relaxing massage but can seem a little disturbing. Hence it is only at the back and neck for use because of softer parts of the body of plastic to very arises.
Were the ball as far as the image heraußen, it would be a perfect massage part.
