Dislocated and broken my ankle in 3 places so in a cast. I’m very active so found it incredibly difficult being unable to move without crutches. I found the IWalk3 on internet and read many reviews good and the minor criticisms. I also, watched the tutorials on YouTube. I can’t praise it enough. Incredibly prompt service, All you need to know regarding this product is on YouTube. Which was brilliant. Putting it together was pretty straightforward using the tutorial and using it has freed up my hands enabling me to struggle less getting around the house. I’m slow on it because of my injury, but it’s worth every penny. Thanks very much.
