My 3 year old loves Dora so I got this set for him. When I was reading the reviews, I was amazed that a set of good quality, hard cover books were so cheap. I guess I didn't pay attention to the actual dimensions. When it arrived, I was shocked to see that the books are only 3"x3". I thought my son would be disappointed but he seems to like it a lot. So I deducted one star because of its diminutive size but gave it 4 stars because of the consistently high quality content of Dora books. Get this for your kid. They will love it...and they can't destroy it so easily because the books and pages are hard bound.
