Just got back from two back to back vacations and really put my luggage to the test! After being loaded and off loaded on 3 airplanes and a cruise ship, my silver wonders passed with flying colors - even the TSA agent who decided to use them as a bowling ball and pins could not damage them!!! The TSA approved lock was a nice feature on the largest case. The silver/black color is more platinum grey, with a textured surface. Wheel systems are the best - very easy to move in any direction. You can stack smaller pieces on the top surfaces - might want a bungee cord for extra security. Just a great set of luggage all around. One tip: these cases hold a ton of stuff and it is easy to pack more than 50 pounds in the largest one, beware it costs MONEY if you go over the weight limit on airlines; not to mention the back problems you might encounter lifting these sturdy pieces.
