Great light. Other lights attach better to bars and helmets.
This is a really nice looking and performing light. Haven't real world tested the claimed battery life but I had no issue on a few hour ride switching between the different brightness levels. What I did have issues with is it staying put on my handle bars. I didn't try both handlebar attachments but figured the smaller diameter would have worked. It was raining and I have carbon fiber bars so maybe that had something to do with it. I ended up attaching it to my helmet and it moved around a lot less, maybe because my body was taking most of the shock. This brings me to another issue. The helmet attachment is pretty big and the straps that are provided are junk but at least it is included unlike other brands. I ended up buying new velcro straps off Amazon. I bought it as a helmet light but it does look good on the bike and I'm pretty sure if I messed around with it I could get it to stay pointed in the right direction while on the bars. Other lights do attach better to both the handle bars and your helmet. It was on sale when I bought it and at the price I paid, I would definitely recommend it to a friend.
