They make you look so much better in a collared shirt. I've been surprised by how many guys didn't know about them when they asked me how my collars stayed like that.

The only complaint I have is that in the time I've had them 2 of the magnets have actually cracked. I have been careful to not let them smash together, and they will so Watch Out! but sometimes you can't help the magnets coming together, 2 of the 6 broke. Not a huge deal, but still a pain.
