I wanted to try using packing cubes and I found a good deal on these with a lightning deal, so I took the plunge. I do like using the cubes for travel and will continue to use cubes for my future trips. These worked well for my first trip, and they fit quite a bit of clothing. Toward the end of the four night trip the zippers failed on two of the cubes. I'm not sure I'll be able to fix the cubes, but maybe I'll still be able to use them in some capacity.
