I have tried them all and prefer the Firenock. No magnets, no little fragile wires and they work every time. I have over 300 shots on my "test" nock and it has worked every singe time.

They are expensive but worth every penny to me because they actually work every time. I'll pay extra money for quality. If I had all the money back that I spent on all of the cheaper Luminoks, Tracers, home brew, etc... I could have a Firenock in all 4 dozen of my arrows.
