To see all comments that praise this bag, we must believe that I came across a bad play. Plastic hooks squeak enormously home, as and when not. Being adept at walking, it becomes quite painful to have to carry everything by the handle; I did not expect with a Case Logic bag.
Too bad, because everything else is of good quality and inspires confidence for the future. But definitely, the 4kg to fingertips, in everyday life, it does not.
