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.
Replaced the basic Dell network adapter card in two Dell laptops with these cards and Wi-Fi connections in both vastly improved. One computer previously had continuous dropped connections and new card completely solved this problem. Highly recommended!
