Wow! I LOVE these!!! Bought them for a trip to Europe with my wife. These suitcases lasted 3 weeks, 5 countries, and 6 cities. They were checked, carried on, and literally ROLLED for miles in each city. If I could buy again, I would but I don’t need to as they are still in almost PERFECT condition, barely look used. The smaller one received a small scratch but is merely cosmetic and not noticeable. The size is AMAZING!!! So roomy, and has a secret pocket in bottom I didn’t notice for at least 2 weeks!!! I have gone through 6 sets of luggage looking for a set that is durable and long lasting - finally found them!!! BUY THEM!!!! also the lock works great, easy to use and doesn’t stick!!! Also worth noting for 3 weeks we packed the small and the medium size only - and had more than enough room!!!! The smallest one can be carried on with any airline; I would check the medium and large.
