We are using 3 massagers of jsb already in our family and this was our fourth purchase from the brand. And like always the company did not let us down. This knee massager is at par with all their massager products we have been using for years now
Intially I was thinking whether it will work properly or not, but it actually works and releives the pain leaving the heat effect even after you remove the massager from knee. Having two of this to put them on both knees would be even great. They should really offer discount for people buying two of these. Only thing I do not give a 5 star rating is the cladding inside and the belt position in center as shown in third picture, instead if the belts were drawn from those circles I drawn, it would have provided nice seating and pressure on the knee. Also thick cladding should have been given. Go ahead and buy, you won't regret it.
