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 haven't used this yet, but I am happily surprised by the quality of the backpack. Even though it folds into itself (and this is ingenious!), the fabric feels strong, not flimsy at all. I thought I would have problems getting it back into it's pocket, but it's really easy to do. It's a good size, with lots of handy pockets - I'm sure I will get everything I need into it. Very happy with my purchase.
