This knee walker fits my smaller body (5'2) better than other ones.  The knee pad is also softer and more padded than some others.  I find it's a little more tippy than my previous one, but an extra wheel came with it that we can attach on the back, which is great!  I mostly use mine indoors and it's been a lifesaver - it allows me to do things around the house, particularly the kitchen, hands-free.  I also use it to elevate my foot (like a foot rest) when i'm sitting down.  Overall, I'm very happy with this knee scooter!
