I bought this item from Acorn, thinking it looked like a fun cage for my Hamster. My assumption about the fun factor was right, but the wheel (which moves around the blue ring as the hamster runs!! How cool is that?!) is so noisy! I didn't realise until I went to bed, that the wheel moves around the blue bit and shakes the whole cage! Apart from the noisy wheel, the cage is awesome. The eXtractable petting area is great, giving me easy access to my Hamster. The slide seems to be good for the Hamster, but I've seen my Hamster jump from the top of it once or twice... But that might just be my Hamster! I'd recommend this Cage to anyone who wasn't keeping it in their bedroom, because of the noise of the wheel.
