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.
This item is exactly what I needed I am testing some old VCR/VHS machines and needed a blank tape to use. I didn't have any tapes I was willing to use in case the tape got destroyed while checking out the machine. Thank you for this product.
