I got a 4 bag set of nylon luggage for $100 about 10 years ago and they lasted 9.5 years. My next, more expensive set ($400ish) lasted about 3 trips. They were ballistic nylon, but the placement and quality of the zippers meant they got rubbed a lot and failed quickly. The nylon itself was fine, but intact zippers are kind of important (the zipper pulls also came off almost immediately). I decided to spring for better (more expensive) luggage and researched for a long time. I expected to be really impressed with this luggage after all the great reviews I read in Amazon and other places. I couldn't find much difference in price among retailers, so I figured it was too good to be discounted (!). I ordered four sizes. Only one came in its original packaging. Two came looking like they had already flown around the world and hit every airport. I returned them (Amazon handled the exchange expeditiously, as usual) and either got one of the same ones back or another just as scuffed. I gave up and kept it. I was also disappointed to receive one of them on which one of the rivets attaching the name plate to the bag had broken. They are not as sturdy as I expected, but they haven't failed yet--after one cross-country trip. I was also disappointed to receive one of them on which one of the rivets attaching the name plate to the bag had failed. The wheels and handles seem pretty sturdy, and I am pleased with the small roller bag. It fits, wheels first, in the overhead bin of even a small commuter plane, and its handle allows me to wheel a briefcase on it. All the bags have a lot of pockets--maybe too many. So far so good, but I'd feel better if I hadn't paid as much for them as I did.
