Not much difference when the unit is switched on or off. The vibration is not sufficient to massage the muscle, if you are looking for a deep tissue massage I would buy a different brand.

Well designed & efficient. Product is ergonomically shaped to reach all parts of the body with ease.

Very good

Have only used a couple of times, but it helped my painful calves

I like the lightness of the product but the engine is really too small to give a deep massage

Value for money
