NO STARS - NEVER WORKED AT ALL
and they wanted to give me back half my money to keep it...IT DID NOT WORK WHY WOULD I KEEP IT.....rather ridiculous.<br /><br />My niece had one from WISH but I like dealing with Amazon...but watch your sellers because I ave had a few that were listed as prime but I had issues returning the item.<br /><br />Hers worked on my knee.  I was so thrilled to find them on Amazon...but IT NEVER EVEN WORKED...WOULD NEVER TURN ON.
