For cons, I did not pay attention when ordering the book dimensions.
I was rather surprised by its size 26 x 15 x 3 cm. But most suprenant may be paper quality!
One has the feeling of holding hands the new paperback edition of the telephone or any botin distance selling catalog is a store with a poor quality paper.
In short, the pages in glossy paper are fairly thin and mark quite easily! A Handle with care on pain of the corner very quickly, especially with a child.
This book would have benefited from being in A4 size, as a lot of other book on lego and a hardcover
So, from the book format, I find it a bit expensive!
