Reinforce the straps or they will fall off. My straps didn't last even three days of use.

Really big. If you like big backpacks, it's cool. But I don't really like big bags... And it's a little awkward trying to get things out of it when it's sitting flat on the bottom. Really flimsy. The small zipper pouch can't hold some of my pens and pencils because they're too long. Other than that, you have a lot of space to put your things in.
