We received these today and have looked them over carefully. The quality seems better than that of luggage that we looked at at a much higher price. The material seems very durable, and the luggage has great reinforcement on the corners and the bottom. We are very impressed. The only negative is that they will NOT fit inside each other unless two of the wheels are sticking out. We did not want to force them so ended up storing the smallest in the largest one and will store the medium one separately.
