We love these books and have ended up buying pretty much the complete collection. These books are one of the few things that our kid is willing to look at and play on his own. He's tried his best to destroy them - chewed them, stomped on them, etc - but the build quality has withstood it all. And this is our fav in the full series. Love the mirror, and it has the most variety of stuff to look at. Love these books and I usually recommend them to all my friends.
