I can see pros and cons. I have a friend who uses a wheelchair and I have helped her with both an electric wheelchair and with braces and crutches. The braces that allow someone to stand can be very uncomfortable and I don't see how this device could hold someone up without some sort of brace-like device. Also, it has one of the same problems as an electric wheelchair. If the motor malfunctions or runs out of charge you have a problem. The wheelchair my friend used at college could not be pushed by her and she could not disengage the wheels from the motor herself while sitting in the chair. She almost always had someone walking with her just in case. When the motor was disengaged the wheelchair was about like a car with malfunctioning power steering. If this thing malfunctions while someone is using it will another normal sized not particularly strong person be able to help move it and the person in it without accidentally knocking it over?
