I always made fun of my riding buddies that had them, I didn't see the need. I put one on my last bike and now I use it regularly. It's the kind of thing I didn't think I needed until I had one........I probably ride a lot more aggressively I'm guessing than the guys above that don't see the need for one. It's not necessary but it's a valuable resource riding the twisty back roads that I frequent. Plus it's just damn cool.......
