Video at Amazon.com View our two chicks playing very happy with it, mostly at night, where it's actually even a bit louder! Construction is very simple, which I have the curved higher parts replaced with flat. The ball then does not always remain hanging and runs completely around what the two much better like! Too bad I only find that you can not change the battery of the ball, which really should not be a problem from the preparation! That is why a star deduction!
