Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
Bought this for Mat got for our grandchild haven't had to use, but it was delivered by email in a very short time after purchasing. I will say I bought bc of reviews and what it covers and the price. Don’t think I’ll need, but great price of mind.
