My son loves to read..even enjoyed the Thomas The Train books as a child and it was hard finding new adventures for him. He loved this...until he tried it out on his own...and the book fell apart.. Poorly made book. A few pages came off. Very disappointed. I am sure this won't last long. It's definitely not worth $24. We returned it. What we like about it- small book, pictures of trains & firemen.

Ex Output:
Bad review

This is an excellent product. I also have the leather case with magnetic closure. Great combination. Works as advertised. My favorite feature of this product design is its ability to stand at all possible directions. Very convenient. Highly recommended. Buy it. You will love it too. Thank you Amazon for supplying such great products.
