I bought the comfy handle crutches because I had a knee injury which wasn't healing quickly and I wanted to get out and about. They were a brilliant buy - easily adjusted, comfortable on the hands and sturdily built. I used both to begin with and then just one as my knee improved, which gave me the stability I needed. The crutches gave me the confidence to get out and about again, having been stuck indoors for some weeks. Highly recommended.
