Bought this bag cause I just got a new lenovo 15.6" laptop. I'm doing my Masters and I must say that I love this bag.Firstly the delivery time was as promised.Second the bag itself looks and feels very durable. The zippers have a good feel to it. Not cheap or fragile and not difficult to run up and down. The pockets and spaces(capacity) are sufficient and also does not seem to be cheaply made(thus far). The straps are comfortable. Not to think or too thin. Not to firm yet not too soft.The overall look of the bag when filled is very sleek (double strapped too your back). The handle grim to the top comes in handy.. At first I thought it would look obvious and stand out (stick up) but it does not. Has a durable feel to it and not feel like it will rip off the bag itself.
