Just a brilliant product ! Ordered with an air of scepticism, but when the iWalk2.0 arrived and was unpacked, it soon became clear this could be exactly what I needed after an Achilles tendon operation. The well packaged product cones with full documentation, online videos and easy to follow assembly instructions. Within 10 minutes, I was walking around the house unaided, carrying a glass of water and the packaging box around with ease. 5 minutes later, I was attempting the stairs. Sadly though the tablets I take meant a long term relationship with the iWalk2.0 was not to be, as I suffer from muscle cramps. These almost debilitating cramps occur when my leg muscles are fully contracted or tensed, and, meant that having my leg captive in the iWalk2.0 brought on the cramps. A quick email to Peglegs UK, and the crutch was dismantled and returned for a full refund. Sadly the iWalk2.0 wasn't for me, but I really wish it was !! This is a brilliant product.
