This is a strong little machine. Works well on my sore muscles (hiking, jogging, yoga) & helps with recovery time. USB power supply & fast to recharge. I'm ordering another one for my spouse. Thank you, Overstock!
We bought these stools to use in our massage school clinic. They have held up to light use, although on a couple of them the plastic bracket around the legs split and came off... no worry there, the stools still function without it. For the money, we are very pleased with the stools. They were about 1/2 what we would have paid at massage supply places.
