To calculate the overall star rating and percentage breakdown by star, we do not 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.
This was just 5 RAT kits. Despite the chatter that these were virtually impossible to get, and once ordered delivery would be in 10 days, the RAT kits arrived in 2 days. Very happy with the entire process. Thank You!
