    1. good light great price
      Purchased two both working great. The price is excellent. I did manage to break one of the retention straps on the mount on some single track but it was a pretty decent hit on a big rock and light was fine. I would rather have a strap break anyway.

      so far I have around 500 miles of riding in total on lights pretty ruff terrain.

    2. Satisfied
      I was not expecting such a high-quality light for the amount that I paid for this thing. So far I have not been disappointed by anything I have bought from O Light. Well done!
