this is one of the best massagers I have ever owned. I am still using it to this day! About 2 years later! It has maintained its intensity and sleek and smooth exterior. Takes a charge well and lasts a long time Once charged. The only negative about this product is that after two years the “skin” has gotten loose and spins around the device occasionally so the button doesn’t line up with the markings for the button. I still give this product a 100% 5star review despite that small flaw.
