I had one of these a long time ago but didn't use it much because it wasn't doing much for me at all (like other posters) ... Wanted to suggest checking out a couple of other possible exercise items to consider for low-impact/no trouble on knees .. the elliptical machine and the recumbent bicycle ...
Usually Sears department stores have these (and other) items on floor display so if you have a Sears near you, perhaps you could check out their display models.
Good luck!

I had one pre-surgery. With my arthristis is was easy for me to use.
I liked it, my husband used it too. My surgeon after surgery did not want me to do anything but walk for months so when we moved I gave it to a friend. I followed the exercises on his video and felt it gave a fairly good workout. Also felt that any movement was better than no movement at all.
Disadvantage to this is that you have to have quite a bit of space for the leg/foot things to move back and forth. So if you want to put this in a limited area of space, it will not be usable.
I bought one about 4 yrs ago and I hated it. I felt like you werent getting any benefit out of it. After 30 min it would say youve burned like 50 calories. I could not stay situated on it and was uncomfortable having to constantly re set my feet on it. I gave mine to my mother in law and she sold it in a yard sale. She didnt like it either.

I had one thinking the same as you because my knees are really bad that it would be low impact. It was fine for my knees really bad for my lower back. It hurt like hell to use it. I took it back within a month. I bought a sit down bike and am getting ready to buy an ecliptic rider which is not bad at all for knees. Good luck. Wendy
