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.
The price on these sleeves is excellent compared to alternatives. This case fits well in our charging carts and provides snug protection for our Lenovo Chromebooks. I rated durability at four stars because we haven't put them into student hands yet. I'll update if the zippers endure.
