I have been using it for 1.5 years for laptop transportation (15.6) but also for various other uses (trips, etc). If we only focus on laptop transportation, it does its job and more, but as soon as you add the charger and some other small items like a mouse, a bag with things, etc, it gets filled up and becomes inconvenient.

Two years ago I bought the Thule with 32 liters for 40€ on offer with free shipping, when they realize that they sell bags and not jewelry, then we can discuss about buying. I don't argue that it is very good quality construction and with many compartments, but when you buy the largest size for 40€ then one can understand if the purchase is worth it or not.
