This one is always divisive. Some people think they're ugly and useless, others think they're good to keep on to protect your spokes in the worst case scenario.

I just got back from the garage from cutting mine off (and unfortunately it wasn't a low quality/thin one so it took forever). I'm not against them per se but after about 1200km of riding, I noticed that it started to rattle and it was annoying me.

What do you guys/gals/pals think of them?
