Review on WishLotus Hamster Ball: 14cm Small Pet Plastic Exercise Wheel, Golden Silk Shih Tzu Bear Toy - Relieve Boredom and Increase Activity - Jogging Wheel for Hamsters by Kathy Miller

Works well and is good value. The son was initially tormented, but after taking it apart a couple of times, it became easier to put together. These hamster balls need to be tight when assembling, so assembling is difficult. This one wasn't as thick as others in the past but so far I find it sensible to reduce the manufacturer's weight to make it a bit thinner which seems to help small and young hamsters. The purchase of this hamster ball was worth it.
