My wife and I are headed to Tanzania for a safari later this year. She purchased a similar (other manufacturer) packing cube set and I purchased these Gonex packing cubes. Both sets were the same price ($29). The Gonex had an additional two packing cubes and one extra laundry/shoe bag. Both of these sets are very comparable in size, and both sets seem to be well constructed with adequate zippers and zipper pulls. The seam stitching on both is also sturdy. So my assessment is basically that Gonex may be a little bit better value for the money simply because you get a little more for your money. Now, as for packing cubes. I traveled, by air, almost weekly in my career for 30 years. I used a roll-aboard almost exclusively. Had the packing cube system been available back then, I certainly would have used them. They organize shirts, underwear, ties, pants, etc. very effectively and keep them neater than free form arrangements in suit cases. I highly recommend this concept, especially if you are going to be traveling and making multiple stops in one trip.
