Had a nice note today from Dean Edwards:

From a personal point of view I would recommend the iWALKFree to anyone with a lower leg, load bearing problem and please use my comments as a recommendation on your site if you wish. The iWALKFree enabled me to get around the house with my hands free and function as close to normal as possible. To be able to make a cup of tea and carry it back to my seat in front of the TV, on my own,  was major progress after a few days of losing the use of my hands with traditional crutches!!

Would recommend to anyone.
