I had to recently throw out my Wodent Wheel/trimmer because it got pretty dirty, and with my new cage, it bounces around so much (its zip tied to the bottom of the cage) that the noise is driving my girlfriend and I crazy.
I saw these Stealth Wheels and saw that them have an option to side mount them, like the Silent Spinner one I already have. And they also have a sandpaper-like track like the Wodent Wheels do. It seems a little better than the WWs because it is a little more open design with a "fence" to help the gliders feel secure.
It seems a lot better, although its a little more expensive than the other options.

Anybody have any experience with them?
