I bought two of these bags from QVC (and I just ordered a 3rd from Amazon today) for my husband, who works overseas and must pack in everything he will need for 3 months.  He lives in a VERY small living space when he's there and doesn't have room to store full-sized luggage.  So, here is the deal:  these suitcases hold a ton of stuff...I mean a ton!  Yes, the stuff can shift...the only part of the bag that is hard is the base...so you need to pack accordingly...heavy stuff on the bottom, etc.  But they are designed for a specific purpose.  I don't think they're great for travel where you won't be unpacking your bag and instead are doing two-day hops.  Yes, the stuff can and does shift...the only part of the bag that is hard is the base...so you need to pack accordingly...heavy stuff on the bottom, etc.  (I just ordered some packing cubes to see if they will make it even easier to pack wisely.)  With tens of thousands of miles on his bags, neither of them have ripped or broken.  We are really pleased with how they've worked out and think they're great, if you understand how to use them.
