My husband was up and walking within minutes! He's found it easy to climb stairs but descends backwards, which is far easier than forwards. He has found it quite uncomfortable on his knee after a short time of wearing it and feels it would benefit from additional padding. It is quick to remove but it can be a pain having to take it off every time you sit down. Hinged Pegleg could alleviate the need for this. That said, it is an amazing piece of kit which gives the wearer greater independence and we would not hesitate to recommend it. Jerry is a star, very attentive and nothing is too much trouble.
