The Superflash is, indeed, a bright taillight. If you get one, use a ziptie or rubberband to attach the light to the clip. Mine flew off when I went over a bump in the road. Having read many a review since, I don't believe this to be an isolated problem. I was in a paceline at the time and wasn't really in a position to stop. So, I lost the light on my third ride with it. When I talked to Performance about it, they told me they could only give me a refund if I returned the light. Uh, that was the point in needing a refund in the first place. I use a Blackburn light now.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
