You're being superstitious. I've heard nothing but good things about Zebralight fixing and replacing lights for free. There was a thread a few years ago with pictures of a light destroyed in a motorcycle accident, having been scraped against the asphalt long enough to make it almost unrecognizable. Zebralight replaced it, no questions asked. If you trust your Zebralight, then it is only rational to trust Zebralight. Trusting one and not the other is cognitive dissonance. If you want to mod your Zebralight, Bob McBob is your guy. If you want your Zebralight serviced, you send it to Zebralight.
One land, one king! That is my peace, Cornwall!
