I just recently received my backpack, it's great. Heaps of space and a good range of pockets and things for storage. Comfortable to wear, light and a good size. I like the hard shell style of it – it doesn't just collapse in on your things.
Only nags are that it is only really freestanding if you unzip the front pocket completely, or at least that is my experiece; and sometimes the zips are stubborn on the corners.
Overall it is a very cool bag, and good value for money.
