Great product. Have had no problems with it working properly. Hinge does come apart if pulled, but snaps back easily. I think if the books are treated like books and not toys then you probably won't have any issues w/the pages bending (and not working) as they are pretty sturdy.
My son got this for his first birthday but didn't show interest into until he was 18 months old. Now he loves it. It works well and he knows how to switch it between story and interactive modes. It's great for trips in the car to keep him occupied. Overall, a good toy for little ones learning to read.
