I have seen a few Below The Amputees saying this crutch is great on social media. Since having my amputation in March I have had a few setbacks which was stopping me getting my prosthesis. After booking a holiday abroad, I thought the iWalk3.0 would be a great bit of kit to get me into the pool as no hoist was available. I know it is not advertised as waterproof, but if I could get into the pool then take it off, it would make my holiday so much better. Although the holiday is still to come, the first time I have walked properly since my surgery has been with the iWalk. I was nervous at first, but soon felt more comfortable over time. Being 6' 5" and of a big build I had to do some checks via the website to make sure I was suitable to use it. May I add that the instruction book is a QR Code which takes you to YouTube videos on how to build, adjust, wear and use the iWalk. If you are not tech savvy, you may need someone that is. The videos are really helpful though, and made the process much easier than if it was just text and pictures in a instruction manual.
