I love eBags packing cubes. I own two sets of eBags and I decided to purchase a set for a friend of mine as a gift. They making packing so much easier and each bag holds a lot. I know what I am packing in each bag. You can easily arrange the eBags in any sized suitcase. I use them in my carry on and for my checked bag. When I get my checked bag my items are not scattered all over the place. They are nicely packed which makes unpacking so much easier. I sometimes leave my items in my eBags and just take things out as I need them. The bags are durable, lightweight, and as said I found I can pack more with my eBags than I could if I was not using them. I highly recommend these bags. The price is worth it and you will have them for years. I have had mine for at least three years. I have packed to them to max and I never had a rib or tear in my eBags nor did the zipper catch on anything when I was packing or unpacking my clothes. LOVE this product! :)
