Am very impressed with the value of this jigsaw book.
Nice, colourful pictures, with lots going on, which is exactly what my son (21 months old) loves in a book, lots of items he can learn the names of. The jigsaw is slightly beyond him at this age, but he likes pulling the pieces out and getting my help putting them back in, so I would imagine over the next few months he'll be more and more able to do it himself.
Have seen another review stating that it's not child proof - seems to be solid enough to me, so guess it's more of an age thing - probably 6 months or so ago, I could see my son chewing/biting/destroying this kind of thing, but I reckon if your child is at least 18 months old, you shouldn't have as much a problem with this kind of behaviour, so could buy this book without worrying about that other review.
It's really good value, 9 nice big jigsaw pieces on each of the 5 pages, each with an interesting scene.
In summary, great value jigsaws, perfect for probably 18 months up.
