Customer Reviews for VEVOR Cat Exercise Wheel, Large Cat Treadmill Wheel for Indoor Cats, 52 inch Cat Running Wheel with Detachable Carpet and Cat Teaser for Running/Walking/Training, Suitable for Most Cats

Easy assemble, Smooth, has small gaps, and is sturdy. Comes with a screwdriver that isn't too bad. Stop lock is secure. The wheel started rubbing against the base a little even after screw tightening, so I just turned the wheel around. The only negative is that it would be better if the screw holes were countersunk.

I was worried my cats would not use it. I set it up and let them sniff it out before trying to get them to use it. I used the toy it came with and a laser pointer to get them started but there are videos out there that offer different approaches. So glad I took the chance and spent the money.

This was super easy to assemble, and or cat loved it right away!
