This is a fine light for commuting, but the mounting is a bit clumsy. I ended up mounting it vertically on the frame headtube and it worked surprisingly well. But on the bars, its not great. Still, I would recommend it.
You know it is kind of well designed. Easy to mount on bike, it comes off and on with ease, and when it works it works good with good light that is easy to see. However, it is hard to turn on and it will not turn off, unless you take it apart and pull out battery then put back in.
This is a low cost option great for a city rider like myself who returns home after dark in the winter. It is easy to install, provides a bright flashing setting that keeps me visible. I've given them to my fellow riders and put them on my kids bikes. For the money its a very good deal.
