Finally a book my 18 month old loves to read! If your child is like mine and has a hard time getting through a book, give the sound books a try. This one has been helpful because my son loves vehicles and anything that has wheels lol! At first he just wanted to press the buttons (no big surprise there) but now he is actually wanting to me to read it. The sentences or phrases are not so long that he becomes bored too fast and he has started making the connection from the pictures to the buttons! We read one page about the tractor ect and he is so excited to show off and press the buttons :)The sound quality is good, a little loud but definitely better than being too quiet. Heads up the semi truck sound HONK can become annoying if it's pressed repeatedly for a half hour lol but if it makes your kiddos happy its worth the sacrifice.The book is ten total pages (both sides) perfect length in my opinion for a toddler. There are tabs on the inside pages that make it easy for little hands to turn the page.The value is more than fair in my opinion especially for a sound book! I was actually skeptical becauase of the price comparison to other sound books but niw I will be purchasing the rest if this line. The batteries alone probably cost half of the price and will likely last for years! When I looked at the batteries they are not the cheap ones and are not the kind that can bust or leak! Comforting knowing it's something your child plays with.Just a heads up too, when this first arrived the sound was not working. I almost thought the batteries were dead but after opening the compartment realized one was just popped out, put it back screwed the plate back in, but not too tight (still tight enough it cant be pryed open though!) or it wont work for some reason. Other than that I am completely satisfied with this purchase.
