I have had two. I bought them both myself as one of my friends said he was going to get me one but never did. The first one fell off while riding. It hung in the center of the bike below the voltage regulator. Riding across Texas I felt like I ran something over, I hadn't seen anything in the road so I didn't know what it was till a few months later I noticed my bell was missing. The second one I tied on with leather so the split ring didn't wear through the pewter. That one was still on the bike when I sold it. Needless to say I am not superstitious, rather I believe in good karma. But it doesn't hurt.
