I have problems with my feet rolling inwards which gives me pain in the leg muscles sometimes. My physio recommended these and they have made all the difference. I can walk miles now without soreness. I will definitely keep buying these.
A good speaker which gives clear sound without distortion at loud volumes. It's not concert hall quality but you wouldn't expect it at this price. I bought it to replace another in motion speaker which had problems with on/ off switch. And was happy to get the same brand.
