The i-Walk 2.0 gives you back the use of your arms allowing indipendance from crutches, a sanity saver for anyone who is independent. After watching and researching all i could about the i-Walk 2.0, fitting and using the device was trouble free although using it for long walks on uneven ground is difficult but not impossible. The device is well built and easy to construct, again although a few minor tweaks would make this device better such as an additional knee pad to bolster the area between the cast and the leg bed of the device. I have been stopped in the street by people asking about the device and i have nothing but praise for the device and inventor.
