Really? That would be incredibly disappointing. I have several other much more expensive lights and part of what I like about this little guy was the price. If I lose it, I won't cry for a week (I lost a X400 on an ATV ride and was pissed for a solid week).Their is a youtube video where they tested (3) and they all flew off during live fire. They may have not installed it correctly so..... It is a unique looking light though.
