My son collects books that sing thanks to the small chips is pressed each page. So was able to test the durability of batteries books, the quality of the songs, the quality of the book itself. I can tell you that those of Grund collection are the best in quality of the pages, the voices are beautiful and sing very goods, batteries last longer than other books and from succroit cheapest in 9e95 General, instead of almost 15 at their competitor. I really recommend it! In addition, that there is absolutely magical at Christmas, can not wait to give it to my son. The songs are too cute, what well wait until Santa Claus. There are songs: Petit papa noel, Snow White, We wish you a merry Christmas, Jingle Bells, my Christmas tree and Silent Night.
