Great content in the book and my son loved all the music and sounds the buttons made. However, after just a few days of use and change of batteries, the buttons no longer made noises and the songs no longer played. He loved it, so I ordered another book (first book was a gift) hoping we had just received a lemon. The replacement book started doing the same thing after just a week of use. My son tries to push the buttons but it just makes strange feedback type noises. Would not recommend wasting your money.
