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 found this product to be excellent. I used it primarily to take notes, even wrote essays with it. The only reason I wouldn't give it 5 stars is due to the squeaking noise that it makes on paper. However, great product overall.
