I have been using this for about three weeks at night while watching TV for about 20 minutes.. I have been pleased so far. I think it’s starting to show a big difference, I feel it will take me about three months as I don’t like it turned up to high as it will hurt but every week I have been and it’s not hurting so much. So easy to used, but not a over night thing. It is very good long side eating well too, 😊
