the NS ones suck, i had 2 and the clip/clasp broke on both of them and almost lost all my keys
im now using my Vail one which is pretty burly. they give them to us for keeping info cards around our necks, but i got another one for keys, it's really thick and good colors and even allows you to unclip the key part from the rest of the lanyard via a built in backpack-style buckle
