I waited until I used these on a trip to the east coast to rate them.  They held up well despite several scratches but I am very happy with this product.  I usually take wine with me when I travel and having a hard-side suitcase made that even easier because it was more protection then my previous soft-side suitcases provided.  I love the wheels on these suitcases - they roll very smoothly and can go over bumps in the road and sidewalks without getting stuck.  I would recommend these to anyone looking for an affordable set of hard-side suitcases.
