I don't recommend.
It worked great for a couple of months. It has an internal switch that turns it off if it gets hot inside to keep the motor from overheating. It started out shutting off after 20 min the 1st month, 2 month 15 min, 3rd 10 min, now it works for 5 minutes and shuts off. You have to wait about 10 min before it will let you use it again. then 5 min.... You can't use the massager it it is plugged in, For someone who is in chronic pain as myself, I was very disappointed for the price.
