Pros: inexpensive for first-timers to try, lightweight, holds more than one would think, keeps items sorted and laundry separate, zippers well-sewn, helps me stay somewhat organized despite unpredictable storage situations during a trip, then makes packing up a breeze. The 8-cube set was perfect. I think one was lined for moist items. I found them to be sturdy, though they look deceptively flimsy.The only con: nothing on the outside to signify what’s inside, and you can’t easily eyeball the contents. But that can be solved with a marker. I think I will number them, then keep a list of that trip’s numbered categories on my phone.I went on two cruises this fall; one to a cool climate; one ti a tropical. The first one was without cubes, and drawer space was inadequate. It was a confusing mess, pawing through stacks of clothes. By the end of the trip, my belongings were a confusing mess and I couldn’t find things.I would add that even on prior trips where hangers and drawer space was adequate, it has been challenging hard to keep tabs on my stuff.I am not trying to sell these things, and my review might drive the price up, but I am telling you these are great.Since June, I also traveled to a location in Vegas. The second trip was with the cubes. On that trip, I only unpacked toiletries, underwear, and hanging clothes. Stood the cubes up in the suitcases and used clothes straight out of the cubes.On the tropical cruise, I unpacked underthings and toiletries and lined my cubes up sequentially on a high closet shelf, letting others take the drawers. I learned to avoid early-morning-unmarked-cube-hassle by taking out of the cubes each night what I meant to put on the next the morning (before coffee, egad).After arriving home and resting up for The Dreaded Unpacking, I grabbed a stack of velvet hangers (also affordable on Amazon) and unpacking was so much easierHowever, unpacking *would have been a breeze* had the cubes been marked. Then, I would not have hurriedly jammed things into the wrong cubes, mixing up pants and tops.Highly recommend trying these!!!!
