I bought this luggage because it claimed to be lightweight.. I did have the suit case pretty stuffed, but it was not over the 50 lbs allowed on commercial flights. The smallest piece does not have the 4wheels like the other two bigger pieces. I love the 4 wheel function made it super easy. The durability is great, but the construction/durability of the cloth hinges could be better. Im still giving it a good score for its overall performance.
