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 would highly recommend this product, The darker the room the better the image. Only fault is the USB cable was both too short and not strong enough. It didn't work, but this may have been because I was maybe a bit heavy handed attaching it...Lucky I already had another cord. Overall am very happy with this purchase.
