Hi , all I can say it’s been a total game changer and I’m pain free which is amazing after being in total agony for more than 10mths – I’ve worn it for more than the recommended time around 20mins each time , don’t know how it works but it does , whether it heels the problem , we will see in a few months , totally amazing device , only downside batteries run down quickly and need a full charged one for full affect , but that’s a small price to pay , jus recharge or have plenty batteries
Many thanks
Michelle
