Sharper image packing cubes are ebag's look a likes except of inferior quality. They have a tendency to unravel at the seams due to poor stitching. Is this why you are unhappy with them? Or is it because they are the wrong size? Or perhaps another reason?

My general recommendation if you are looking for maximum light weight is to go for either the Eagle Creek Pack It Specter ones or the new eBags Ultralight packing cubes: http://www.ebags.com/product/ebags/u...uctid=10408193

The eBags Ultralights not only look great but also have a unique spring loaded frame making them maintain their shape when packing them which makes packing easier and also they look great.

My recommendations above are for carry on sized bags for full size larger checked bags I recommend these Travelon ones: http://www.ebags.com/product/travelo...uctid=10359810 http://www.ebags.com/product/travelo...uctid=10359948 These are the best ones for use in larger checked bags. The best ones I have tried for my needs!
