Used these for a first time on a recent multi-week trip. Really made packing and unpacking a breeze. The added benefit was the quality for the price. As good as, if not better than, the quality and size assortment of similar items being sold in the container and luggage stores. I found these cubes to be very generous sizewise compared to other brands (i.e. other brand Large were similar in size to the Travelwise Medium Cube)
