This is a fantastic product and has really improved my mobility. I have a fractured foot and living alone in a three storey house, I was getting about on all fours, with consequently sore knees and shoulders. The iWalk 2.0 enables me to get up and down stairs, carry a cup of tea without pushing it along the floor (heaven) and has allowed my shoulders and knees to recover. I would recommend this product highly. I would also commend Peglegs UK for their fantastic service and being prepared to inconvenience themselves to ensure I obtained the service I needed.
