Bests & Worsts Reviews from Amazon

The item description says this is for reading level "ages 8-11". I assume that is based on the text on the pages, but it's misleading, since this is a maze book. Based on others' reviews, I thought this would be good for my son and got it for him for his fifth birthday. He sat down and completed the whole book in about 15 minutes and said it was too easy. I hope people aren't buying this for their kids who are 8-11, based on the description. It would be nice if the product images included a few of the pages so people can actually see what they're getting.
