I had surgery on my ankle not allowed to put my foot on the ground for 9 weeks, I was miserable on arm crutches. You can't use your hands, can't carry a drink or do anything useful! My neck, shoulders and arms were painful. I saw the Pegleg iWalk on line and ordered immediately! It arrived quickly, My husband assembled it in a few minutes. It is very adjustable. We followed the online video instructions. I had it a little high at first then adjusted it to be very comfortable indeed. It took a couple of days to get used to it then I was walking confidently and able to do pretty much all daily tasks. I got really quick at popping it on and off , it has easy to use clips. It made my 9 weeks in plaster much easier. I have put it in the cupboard just in case anyone in the family ever needs it!
