"My male hamster LOVED this cage from the moment we put him in. He loves the tube so much that he goes up, turns around, goes down, goes up. goes down, and it's hilarious! The wheel is great because it's plastic, which means you don't have to oil it, it's silent, and removable. It's really colorful, and the first thing you notice when you walk in the room. But if you hamster isn't familiar with the type of water bottle being used, you can easily hook one onto the side. The assembly was quick and easy, in fact, two 11 year olds put it together. It comes with instructions but for the most part it's pretty self explanatory. If you're iffy about this cage, definitely get it! It's a fantastic purchase!"
