Not a suitable replacement for crutches. First it takes more time to attach and remove. Second it is heavy and if you are older like me you will notice back discomfort after using it for 5 mins. It also puts a lot of pressure on your other foot and causes me a lot of discomfort. It sits in the corner now. The concept seemed like a good idea at first but did not work for me. I would get a good pair of light weigh crutches instead. Even if they made it lighter a lot of back and opposite foot discomfort. I don鈥檛 recommend.
