Well the one I recieved I was unable to use as it would turn off and on several times in a 5 min window

Checked batteries and all troubleshooting massage doesn’t work. Heat works. Not worth the money

It will do the job, but you should be aware that it is kind of bulky with a thick handle not comfortable in small hands. 11.22.2020 I have to take one star back because I can use only one of the provided three heads (the round one). The other two heads don't sit tight and fly off on contact during the operation. I wish I kept the box to be able to return it.
