"The silent spinner is a very appropriate name.. Unfortunately, like most wheels that are constantly used, it will eventually wear out. If the pet using this wheel isn't very heavy, it will probably last longer than it did for my nearly one pound hedgehog. He LOVES his wheel and ran on it for hours on end at night. The wheel lasted about a year before it just fell apart. I will be buying another one soon. Another drawback of this wheel is that it is curved so that if the animal messes in the wheel, it STAYS in the wheel.. causing him/her to run in his/her own mess. This means you need to clean it more frequently than wheel that aren't curved. Other than that, this is THE quietest wheel out there. Trust me, I've been through every single wheel petstores sell."
