Unbeatable price for a bag of this size. Alienware M17x R4 comes a smoothly with mouse, power supply, documents, headphones, paper, pens, glasses, gloves, cards ... but there is almost no padding, seams all seem rather fragile (much too tense with 10 kg of load ...) and a ramp was torn on the side from the 3rd week (however, not making it unusable bag). I had to invest in another bag to better protect my machine to 2500 euros. The pockets are not overly thoughtful (lack of practical storage as pocket umbrella, "hidden pocket" on the back, compartment door papers in the main pocket, no fixation in the pocket PC). 3 stars therefore, for the excellent price. No surprise: sac less than 30 euros, benefit less than 30 euros!
