Cilegrey - I haven't heard anything sorry.
Rraijjar - Walking is great actually. The pivot point for my knee joint is exactly where my knee is so it bends easily. Also the legs are free floating on top of the boots and not attached to anything so they move freely wherever I put my feet, I could step up onto platforms and walk quite naturally anywhere I went. Until my stilts broke of course, then I could still walk okay but climbing things was difficult. I unfortunately did not succeed at conquering the bane of all the Emperor's finest...STAIRS.
