I am not an expert on space optimization, but I feel that the square shape of this suitcase allows me a few more cubic inches of packing space, which is a huge plus if you are traveling for more than just a few days. We spent 13 days in Europe (Munich, Garmish, and Rome) and I packed all my stuff in this suitcase and a backpack. I also love the 4 rolling wheels. Two-wheel suitcases are harder to roll.

Love how the wheels roll easily and the sleek look just makes it great to travel with. Also love how easy it is to pack my clothes in this bag.

Perfect size to travel with. Maneuvers with ease. Fits in overhead storage without a struggle. Looks fantastic compared to others at the same price. Seems durable enough to last for many trips.

Great suitcase, wrong color. 1 trip only and suitcase all black from airlines baggage process.

Just back from a twelve day trip to Europe and Im glad I went with carry-on only with a cross-body sling bag fitting nicely over the handles.

This luggage is sleek, takes a beating and has incredible maneuverability. It fits perfectly everywhere and I was able to pack everything I needed for my month-long geek trip (granted I spent most of that time in board shorts and boat shoes)

Great suitcase

Rolls very easily and smoothly. Nice all around. Straps and dividers to hold things steady, very durable yet lightweight.

UPDATE: I have changed my review from 4 stars to 1 now that I have returned from Holiday. I was extremely excited about my new luggage set. I loved the smoothness of the rolling wheels and the texture of the suitcase surface. However, when I reached London Heathrow and my larger case came off the conveyor it had a large dent in the side. My trip had barely begun and this was only the first of 2 countries I was visiting!

Nice
