I choose this light because the design and because I has a multi tool that I love it,but maybe the light business is not the strong stuff. When i received it came in nice package and the overall quality was very good. Installed for a ride with my friend inside the city and it worked very good, it was the first, last and unique time that this light worked. I changed batteries, reviewed the old batteries, inspect visually where the batteries sit if any problem , but nothing... this light never shined again.
Never again will buy a product just because I trusted the brand, I will wait to others try first.
