To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought this for my seven year old and she loved it. It kept her busy on the plane AND in the car. He sister also helped. They both loved it. There were a few activities she couldn't do, but we did them together and it was fine. GREAT!
