They are well made and worked well on our Italy Trip, but it was kind of a pain to keep taking the whole cube out of my suitcase in order to take something out of it, because it disturbed everthing else in the suitcase, so I'm not sure I'm a fan of cubes in separating your clothes. Plus, it would probably work better to have only 2 sizes.  Two to fit the width and length of the suitcase, and two half that size.  But if this is your thing, then these cubes are great.  It was nice to be able to see through it so that you know what is in each cube.
