I love the storage aspect of this bag. I love the packing cubes. The suitcase does hold a lot of stuff, and the different zippers to access your items are helpful. It is lightweight. It can attach to another bag.
I hate the way it rolls. You cannot tip it on 2 wheels, which causes your arm to be at a strange angle that can be uncomfortable after awhile. You have to be pulling it just right or it will tip over, no matter how well you try to plan your packing. So that is very frustrating. Verdict: if you don't have to pull it too far, its ok. If you are using as a carry on and it will be with you for hours, prepare to be frustrated.
