This retails for £299, it’s the older version. It was a life saver when I broke my ankle, i also bought a cheaper one from Amazon for £100 but the handle kept coming loose the brakes were terrible and I couldn’t use it outside the house as the hard wheels would rattle my knee. I would say this is really a must if you’re in a similar situation, it allowed me to keep sane getting around outside I could move and have things in the basket (that’s missing but I might find it or you could use something else) and my leg muscles didn’t waste as much as they would have as I kept my body weight on my knee) I also had an iwalk (also listed) but this was much more useful as I couldn’t go that far on the iwalk and it was quite unsteady.
