I had to undergo ankle surgery and was advised by my surgeon that I would be non-weight bearing for 8-10 weeks. Not sure how I would cope with this and the fact that I was useless with normal crutches, I started researching the alternative which is when I came across the iWalk2. Having looked at the video on the Peglegs web site and on you tube, I decided that this was for me and took the plunge and purchased the kwai 2 from Peglegs Uk. It arrived very quickly which allowed me to practice using the device before my surgery. Once I had had the surgery and had come off of the pain killers that I hd been prescribed, I started using the i walk around the house. It was easy to get used to and with more practice I soon ventured out. Although I got some weird looks from people at least I could get around with my hands free.I certainly felt more confident using the i walk than I did with crutches. To be honest, it was bit tiring on the legs at the start but the more I used the i walk the easier it less tiring it became. If you have to me non weight bearing I fully recommend the i walk 2.
