Review on 🐹 8.3-inch Silent Hamster Saucer Exercise Wheels - Silent Spinner Running Wheels for Small Animal Pets such as Hamsters, Chinchillas, Gerbils, and Mice by Heidi Harter

This is a great size for the average Syrian Hamster. It is easy to assemble and fits perfectly in the cage. BUT, depending on where the hamster walks, it loosens the central hub inside and falls down. Then the whole wheel falls off the screw and the hamster is underneath. NOT GOOD. Since hamsters are nocturnal, he could potentially be trapped all night. What a waste of money. There is no need for the center hub to be removable as it is connected to the frame bars with a different attachment. Don't buy this!
