Yes. I have one. Probably 3years now. I love it. Keep a chart when I use it to keep myself accountable. My PD is mild. Diagnosed in early 2011.

Sorry, I am still learning this site - just saw your comment mar 4. It is very easy getting on & off, also the pedals have a sturdy strap. It helps by pushing you a bit faster than you would normally go. It is very sturdy so you feel safe..

I am interested in this also. I would like to know if it is easy getting on and off and keeping your feet in line. How does it help?

Do you have the 100 model or the 200 model? Any idea where I can get a used one?
