Very speedy and efficient service. Unit was despatched within a couple of hours of ordering and arrived the following morning. Various emails kept me up-to-date with what was happening with the order. Before it arrived had appointment with fracture specialist and asked his opinion. He hadn't heard of it previously, but after a couple of minutes studying online, simply said "Go for it"! Tried it for the first time this morning. I am no 'spring-chicken' (age 66), albeit without any mobility problems until current leg-bone fracture. It must have taken about three steps before I felt confident. After that, although not exactly 'pirouetting', was able to bring in a cup of tea from the kitchen and later empty dishwasher and washing machine without any bother. It is actions like this that are so difficult to do when using crutches. I'm expecting also that it will be far less fatiguing. Using crutches I have to pause every 10 or so 'hops', whereas, although not walking huge distances so far with the iWalk, it hadn't occurred to me that I needed to stop for a rest.
