"My Syrian hamster, Chester, suddenly showed know interest in running on the plastic wheel included with his cage. I thought he was sick or hurt, as Chester has always loved running on it. Then, I saw that his wheel was too small. I found one of these wheels in my garage and placed it in his cage. It was bigger than his old wheel, and he loved it! He ran for the rest of the night. I had to go back to petco and buy a new one however; his original wheel was a very UN-manly pink! (although he didn't know- hamsters are color blind!) Anyway,I gave it four-paws only because it squeaks, which doesn't bother me, but it could be annoying to some people. Other than that, It's great!"
