The Silent Spinner is pretty easy to detach from the cage to clean. If you have a calm rat that likes to run it seems to hold up fairly well. However, one of ours likes to hop/run. This is just too hard on the Silent Spinners attachments. It wobbles and breaks down rather quickly and has to be removed because of the awful wobbly noise it starts to make.
To recap, the Kaytee Silent Spinner has a variety of colors, it is easy to attach to bars, easy to clean and nice 12" size. On average I have found it for around $22 at local pet shops. The biggest complaint, it wears down quickly with rambunctious runners.
*** I would rate the Kaytee Silent Spinner with - 3 out of 5 stars
If you are planning on getting a wheel, make sure you invest and get the larger one (at least 12"). They will outgrow the smaller sizes in just a few months and can develop many complications from running on the wheel if not closely monitored. This can include but are not limited to spinal curvature (wheel tail), back injuries, nerve damage and even muscular injury.
