I googled it and found another video. (it's a youtube link)

This video showed some people playing around with the U3-X at what looks like a hotel convention room. There's some actual audio in the video and it sounds like the U3-X is loud.

It looks like you cant exactly use the U3-x as a wheelchair, because I saw people having to use their feet to change directions. I just dont see someone who cant move using this thing. It's still cool, but I'm guessing it's not practical for a handicapped person to use it.

The way I feel right now, I doubt I'd be able to use something like this, and I can walk. (right now I have deep full body numbness, whole body feels like it's in a spasticity attack, especially my back, and I'm dizzy and feel like I'm going to fall over while just sitting here)

I think this thing would make me even more dizzy. I still think it's cool tho. It'd be cool if they could adapt the technology they used for practical use in the handicap world.
