This is my main gripe about bike product$. They just don't hold up. Told my better half, at those prices, I can afford to make *alot* of mistakes at home and *still* come up with a quality product.

I commuted today with mine for the first time. No worries. Because each component went on several long runs separately and held up. Then with everything assembled there was a slim chance that something would run amuck. The light ran like a champ.

Unlike the "engineered" rear turn signals that fell off the *non adjustable* bracket and must stay attached with a dang rubber band and even then may work not work.
