Very good and worth every penny but bear in mind it is cumbersome, especially on stairs, and a little heavy. Once on it's fine but it's an effort to get it on and off between short journeys for example to the toilet or to make a coffee. Improvements would be an aluminium frame to reduce weight and a lever mechanism to more rapidly secure your leg. The handle at top is surprisingly very useful on a long journey making it less tiresome. I am a fit 64 year old man with a very badly smashed ankle and belive it is helping me maintain some degree of fitness because I have my hands free and can go further than on crutches. Practice helps a lot. I began using it at ten days after my accident and my surgeon seemed ok with this but you will need to consult.
