This product is absolutely amazing and makes having a lower leg injury liveable. Being able to carry things and cook as normal is a God send. If I have one criticism it would be that the thing is a bit heavy and could benefit from being lighter, I do appreciate however that this would increase the cost so it is probably pitched perfectly just as it is. It is easy to assemble and use, if you get a chance (prior to surgery eg) - spend some time getting used to it, as standing up from a seated position and managing stairs can be very tricky.
