Very disappointed. Ordered 3 different sizes for my vacation. They arrived just in time only to make my travel MORE difficult. I packed them according the instructions/video with the packing cubes. The would not stay upright and I basically had to carry the bags because they either wouldn't roll or they would roll all over the place. I contacted customer service about returning them. Received a generic, copy & paste response about no returns unless they are unused. Think twice about these bags.
