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.
My new $90 Herschel bag needed this $13 upgrade and I'm more hyped on this awesome little backpack insert than I am on the bag. Works great and I really like how i can just pull it out completely when looking for something and put it back in with ease.
