So at first glance, these things appear to be something you just go out and buy. But are they one of those things that after owning them for a while you realize that you should have gotten this or that instead?
I've seen two different basic types:
Secured by a pin
Secured by threads
I would think the threaded type would be better? Also, how easy is if for someone to just walk up and steal these off your bumpers?
Also, several companies offer them in color or some other coating. Does those coatings hold up to use or will it wear off after the first use or two?
