Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Cons: Internal 'laptop' sleeve goes all the way to the bottom of the bag. This meas if you have a laptop in it and 'drop' the bag on the ground, you will hear the clunk of the device hitting the ground. Small pockets within the 'front' compartment are seal via elastic. This means that small items within these areas will end up all over this section as this elasticated borders does not seal the objects within them. More zipperd pockets would be greatly appreciated.
