Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
This OEM Drum Unit didnt last 10k pages before white striping. This is due to defective drum unit clumping up inside. Techs have reported some defective from Canon are having this failure.
