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.
Granddaughter is 4 and loved this but one of the buttons on the reader is already broken after a week. The books are not ready sturdy either and I’ve had to tape them back together. Very disappointed and was planning on purchasing more.
