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.
Ordered this for a Christmas gift but there was no way to see inside to know exactly what I was getting and the details on the cover were too blurry to read on-line. When it arrived and I finally got to see inside, I was disappointed that there wasn't more to it (more activity pages). Okay, but not great.
