Very good, my cat loves it.

This product is fantastic! Both of my cats enjoy using it.

This cat toy is great, even though my large Maine Coon might be too big for it and I'm unsure how long it will last. However, it provides excellent exercise for my cat. I plan to modify the 3xAA battery power source to a USB rechargeable one. Despite only using it for two days, the quality appears good; my 8.3 kg cat has been biting and dragging it without issue. Now, my cat has a wonderful exercise toy for a long time. **Serious Seller*** Fast Shipped!

The size is perfect. It seems very fast to me, but my cat doesn't appear to be bothered by it. I received it on time.
