Since I first heard of packing cubes, they have appealed to me. Every trip since first hearing about them, I kicked myself for not ordering them yet! There are so many to choose from on Amazon! I read reviews and went w/ Shacke Pak prior to our most recent vacation. Not knowing what sizes would suit us best,  I ordered the 4 Set pack for myself and 2 kids.  I am the one who packs/unpacks for us all, so it did make it nice to arrive at our destination and pop them into drawers. Upon return home, it was great to take a pak to it's appropriate drawer/closet to unpack rather than going back and forth to the suitcase w/ individual items.  Overall I am very pleased with my purchase, quality is very good and the variety of sizes in 4 set pack is good to start with, but I will probably order a few more medium or large paks!
