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.
I purchased this for a baby gift for my granddaughter who had a small baby and lives in another state. She told me that they smelled bad when arrived and did not want to put them on her baby girl. I would not recommend purchasing these at all.
