I haven't had a chance to use the luggage yet, but upon receipt I checked to see that all the zippers worked, the telescoping handles worked, and their was no obvious damage to the suitcases.
This product truly exceeded my expectations; it's everything that is advertised, quality materials, and smart, smart design. It was definitely designed by someone who travels. I especially like the hidden laptop compartment in the carry-on size. I highly recommend this product.
