nice look and temp seems rather accurate (I'm comparing with my older thermometer). one star off is the display seems a bit busy with all the max and min numbers which i haven't yet figured out what there the numbers relatives to.

Ex Input:
My son is really getting a lot from this. He is 7 years old and has been diagnosed with Autism. He doesn't care to color the pictures but he does all the other activities and you can really see it is helping him. Not to mention he is excited about going through the book. For something that has been so hard for him, it is as if he is gaining confidence just from reading and practicing what is in the book.
