I gave these packing cubes a try after I saw a video on how much more you can get in a suitcase using packing cubes. I was pleasantly surprised that this was true. Packing is one of my least favorite things to do. The cubes help you to focus on the necessities so you don't over pack and I found I packed for a 3-day trip in half the time I normally take. One of the bags came with a seam which had about 1 1/2" unsewn, but given reviews I had read, I knew this was a risk.  It was easily repaired with a needle and thread.  I believe these cubes will serve me well for years to come.
