I have had my iwalk2 for a week now. It was pretty straight forward to assemble and set up. It really is an ingenious piece of kit and has been extremely well designed (no doubt at huge cost to someone) and manufactured to a very high standard with excellent materials, locks etc. I use it every day (initially to the amusement and/or surprise of onlookers) and am currently augmenting use of my crutches, ie I alternate. I find the straps to be a little uncomfortable at times, and think the strap padding could be improved generally. While it is a “one size fits all” I do worry a little that the “platform/ledge” for the lower leg is a lot shorter than my leg leaving my leg suspended a fair bit - the crutch “leg” is extendible but not the ledge. Perhaps there could be options to have a longer “ledge”? Maybe that’s not a big issue - I am 185cm tall and have “average” leg lengths so this must be a bit of an issue for others as well I expect. We have had snow lately so I’ve been unable to really give it a go outside. It certainly makes stairs (with a handrail) so much easier than crutches, and having my hands freed up, while going about the house is a massive bonus. I look forward to better weather and trying it outside.
