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 analyzes reviews to verify trustworthiness.
This makes a nice baby shower gift which is why I bought it. Most people do not think to buy something like this. I realize it is about ten months before the baby will crawl/walk but still most mothers tell me they are so glad they have it when that time comes. I buy it every time I need a baby shower gift.
