This product works as expected. The replaces my lost unit an the stimulation of the muscles is much better. With fresh batteries the stimulation can be intense. I would purchase this product again.
I was impressed with how long the sand paper lasted. I used it on drywall and on a metal table and the results were as expected. When I run out I will get more of this.

Good so far...wait for final judgment.
I have a young car and had heard about this from a reliable Mercedes Tech. I check gas mileage every tim and will be verifying this product increases fuel economy. It does take a tank or two before the effects are present.
