Not sure why so many reviews are critical of this backpack but it is a great value and works fine. I wonder if this same product/model # was used for a different backpack? Now for the price, it does seem not to be made of the highest quality materials, i.e. feels a little thin in the fabric and zippers but it is still VERY good. I wouldn't hesitate to get one again based on the quality and value. I would challenge anyone to find a better backpack at this price. Having said that, my new 17Inch laptop is a little snug in the backpack. I feel like I have to be careful when zipping around the edges of the laptop as to not catch them in the zipper and possible scrape it. I would still recommend it for a 17 inch just be a little careful. Thats why I gave it a 4 stars out of 5 for performance. Lots of pockets and rooms for mice, power cord, etc.
