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.
Our 8 year old LOVES the Mighty Robot series! Our only problem is the binding- the books tend to fall apart, a page slips out...then another...then you have a frustrated 8 year old. We have the entire series and it has happened with nearly every book. BUT, we LOVE the stories!
