I purchased an Iwalk-2 as I am on the waiting list for talo-navicular fusion which means I will be non weight bearing for 6 weeks at least. The thought of using crutches with all their limitations was not an option. After looking at what was available I purchased the Iwalk. I am not disappointed. It was easy to assemble and comes with comprehensive instructions not only for assembly but how to get yourself moving with it too. Once I had made the adjustments and strapped myself in I was walking quite confidently within minutes. I shall use every day for a short while to get familiar with it and when my surgery is done I will be fully mobile, non weight bearing and able to get on with my life!
