To calculate the overall star rating and percentage breakdown by star, we do not 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 bought this shredder because It states it has a capacity of 10 sheets. Using 80 gsm paper ( common type) it jams if more than 6 sheets are fed in. I contacted fellows who said it had a capacity of 9 sheets of 80 gsm and 10 sheets of 70 gsm. Don’t be misled by these claims - it doesn’t !
