Oh, totally! There's a reason that such mobility aids are so expensive. My point was that things like the "Not a Wheelchair" can be cheap because they aren't used full-time, the same as for the Air Hawk.
There's a lot of people that use wheelchairs for part-time use. When I was considering getting one, I could walk a couple minutes but couldn't go farther without injuring myself further. Having something cheap that could get me some freedom back would have been worth it, even if it's not perfect.
