Finally a belt without metal! As a professional frequent flyer, I was looking for a belt, I do not ever have to pull out of his pants at the airport and then having to shuffle with sliding bushings through security. Each belt on this planet has a metal lock or metal on the belt end! All dung fly! So here a plastic. Proud and confident of victory at the airport Tegel to the security check. Pockets empty, sure! "Your clock ?!" - "Luminox, Carbon polycarbonate case!" - "Aha belt ?!" Shirt lifted up: "Plastic!" - "! Ha Na because komm'n se times by ..." PIIIIIIIIIIIIIIIIIIIIEEEEEEEEEEP The security guard: "Well, too early happy Nehm 's get out the thing and please on tape!" Disadvantage (for airport security checks) to this otherwise very stable and robust belt is probably the material thickness. Although completely without metal it beeps anyway, at least in Germany. Pity! But still good product!
