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.
Shipment was super fast, arrived in 1 business day. Everything is great as explained by supplier especially raspberry case. They also put the heatsinks for you then they cover the pi with cover. All good, didn't have any problem.
