Perfect, clear sound, satisfactory duration, and wonderful images. The 16-month-old baby loves it a lot and it's a nice way to introduce classical music. All three in the series have been purchased.

They gave it to us as a gift and we have had it since it was a newborn. From 3 months old, I started showing her pictures and pressing the buttons for sound, and now at almost 11 months old, she takes it herself all the time and plays with it

Very beautiful book. My little one likes it very much and we read it all the time. On each page, it has a little story about the composer and a button to press and play their piece. It has a total of 5 pieces and you open it at the back. It takes 3 LR1130 batteries which are included when you purchase it. It has good construction, the paper is durable and doesn't tear. I recommend it blindly, it's very nice.

It is a wonderful book with beautiful illustrations and good sound. However, it didn't immediately capture the interest of my child (3.5 years old). I believe it is more suitable for older children.

One of the best books, the illustration is wonderful, the music is powerful, we have already finished the batteries. The page layout is quite good, hard and durable.
