I got one for the winter, and it was fine for getting a little extra exercise. Now that it's summer, I'd rather go outside.

I found I could only really use it when I was watching something on the screen. Watching videos was fine, and so were meetings if I didn't have to have my own video on. The motion was pretty distracting for other people.

Trying to do any work while on it was difficult. I could do a little if I went at a much slower pace than my normal speed. Even then, the static electricity would build up, and I'd get zapped after every time I took a break from touching the desk.
