I have a big bag searched for work. Price super. Stable is well. Place is more like enough available and has incorporated plenty of small pockets. Unfortunately, the shoulder strap is a little too long for people below the 1.70m. Well you can adjust the strap .... however you can then attached shoulder pads do not use or you always hang the bag toward squat. Unfortunately the 2.te criticism is also the shoulder strap. The plastic tab on which the belt is carried out should not have to be rectangular or should have at least tightly. So this always attracts in an inclined position and gives the strap 5cm longer at length ...
Otherwise, at the price you can not do much wrong.
