I don't watch much TV, so when I saw this ad I was dumbfound people would buy it. A Nissan Titan frame with the tires, wheels and axels on it is hooked to a locomotive. A chain is hooked to the frame and to the locomotive. The locomotive is put into motion. The frame snaps up and some how hits a post dead center perfectly lined up on the post?? The locomotive is brought to a dead stop. Some how the light weight chain doesn't snap?? Also the frame doesn't even flex in the commercial?? Then more tension is put on the chain and the chain snaps, at the coupler?? not in the middle of the chain were it took the major shock when it snapped into place when the locomotive was stopped.
