Bests & Worsts Reviews from Amazon

Sadly I cannot give this more than one star...I am not an engineer, mechanic, or handy person, so I do not claim to be an expert with tools, but like others I followed the instructions and watched the video to put this together with as much care as possible. My cats both loved it but, the wheel would derail after just a few rotations. The wheels were not lined up and the constant time and effort of putting it back on finally wore me down to giving up and throwing it out! The concept is excellent but the materials are cheap and having to put plastic/fiberglass hybrid parts together that broke at the slightest use of the enclosed rubber mallet did not bode well for it. After watching the wheel come off numerous times I was really worried for the safety of my two Girls and opted to be safe and remove it! I see some small dog training wheels and will probably opt for one of those since they appear to be made of machined metal and shipped per-assembled. I would rather pay a little more for the convenience of having a safe and ready to go wheel then the frustrating experience of this product again.
