So disappointed

I purchased this bag because I need something that could hold my work items and my school books. I didn't want to have to keep carrying two bags on the days that I had school. The bag was definitely big enough to hold two notebooks, two school books, my personal items, and a laptop. The thing that I am totally disappointed about is that this when this bag is completely full, it doesn't hang right on your shoulders and tends to put a lot of strain on your back. It is hard to carry, and I have to keep adjusting it just to keep it in a comfortable position. It is nothing like I thought it would be and am totally disappointed with the purchase. Now I have to go back to the drawing board and find a new bag for school.
