The iWalk is a brilliant alternative to crutches allowing you to resume some freedom of movement. Personally I think crutches are still needed as I couldn't spend all day on the iWalk. If I spend too long on it I find my knee quite stiff from being bent for extended periods of time, plus all my body weight is now going on my knee as I walk which makes my knee a little sore. I've yet to master sitting down or going to the toilet with it on too! However, being able to put it on for specific tasks - making dinner, cleaning the house, walking the dog, etc has been a life saver when confronted with the restrictive monotony of normal crutches after having broken my lower leg. I would definitely recommend to anyone wanting to regain some freedom if you've been forced into the burden of crutches!
