We bought a couple of these after our very ancient iPod speaker base died. For such a small item, they have really great sound. (And the kids love the changing colors!) Very handy that they are so portable as well!
We love to color in my family. We were pleasantly surprised to open this book to see that it is "clear" in the parts you color (kind of like waxed paper). We didn't realize this when we ordered it. This makes them great for hanging in a window.
