Firstly, I can swim. However, I badly broke my right wrist last year and after trying to swim in my local pool, I was struggling just to float. Recommended by a lady who couldn't swim but was doing 25 metres in about 3 minuets, her secret was a Bedo vest. So, I tried the Bedo belt and yes, it works. Ok, I won't win any technique medals for swimming but it gives me confidence to try to regain the full use of my arm and hand. As recommended by my physio. Well done to customer services for all their help after I unintentionally ordered the wrong size.
