Its kinda funny. I almost always forget that stupid little chip in the step when I trailer the boat, and they always fall out on the 10 mile trip home from the lake. I left one in coming home from Texas to Minnesota, 1700 miles!!!, and the friggin thing stayed there the hole way home. I lose more than I use, they end up disappearing before they wear out half the time. Another thing, what are they a couple bucks? They take 1.5 seconds to install? Suck it up Nancy.
