I gave a 4 only because just got the bag and haven’t had a chance to use it yet. That being said, so far I am very impressed with how slim/compact this bag is yet just how much stuff you can fit into this bag. I built my own, not really knowing what I was doing. For the center I got the c5 and the front and back to attach to it. As I said, really didn’t know what I should’ve been ordering but I like pockets and if you do as well I highly recommend this bag. It’s perfect for all the small stuff that always seems to hide at the bottom of a bag. Overall thus far very impressed, not to mention the engineering that went into this bag is like nothing I’ve ever seen before.
