I'm a music student, and so I needed a bag that could easily carry around both my guitar and my sheet music from lesson to lesson.
I was happy with it at first, it protects the instrument appropriately enough. But after about 2 months of everyday use it started tearing at the seams - the front pockets were very worn, and the handle for the zip mechanism flew off when I opened the bag the other day, as well.
It's okay! But if you're planning on carrying around your guitar for a longer period of time, every day, consider buying something more durable.
