I've been looking for a nice book sensing and this one is really great. Our little one is crazy about it. It is beautifully finished, the images are very cute and easily recognizable for children. There various materials and structures have been processed. Most of all, our son is still looking for the crackle as it is still too small for horn and rattle. But he will surely soon find just as exciting.
The holder is great for the stroller so that the book not even accidentally fall out. At home, the ring is then "converted" to the teether. I would buy the book again and again.
