    Incredibly bad sensor. The sensor is very weak it does not work!

    IF you like batteries over rechargeable/USB/newer tech, the front light seems to work well. It is bright, but be warned, it could interfere with the operation of some computers. It seems well made.

    Blink mode is simple on/off, so no strobe. Pros/cons of various modes are debatable, and documented online. Each case has some validity, between solid or strobe.

    The rear light is very bright, BUT, it seems very cheaply made compared to others like Planet Bike. The plastic seems likely to break after little use. Some have noted the clip snapping off. In inserting batteries, just removing the back once made me feel the tabs that hold front to back could easily break. In this respect, the Planet Bike Flash models are far superior - a shame since this is bright. Other reviews, elsewhere, note the same, as well as calling it "toylike."

    Given the closeout price, I took the rear/red as a soon to be throw-away.

    Too early to tell, but many other reviews say the straps will easily break.

    In the end, on 1st use, I like the front, but it will interfere with many bar computers, so no speed, HRM or other data.

    bought it for my wife so we could go on night rides and commute to work and it is lighter and brighter than my Black Burn X8 which I've been using for years. she loves it and can't wait to use it some more.
