Upon unwrapping the package I knew the strap was way too short for my bars - no room there anyway with a bell and a Garmin. So I tried it on one leg of the fork. My fork is smaller at the bottom so the strap wrapped well around it there. Then I pulled it up the fork, expanding the rubber strap, until it was secure. But then it pointed too high on the road. Fortunately the light pivots on its mount so I was able to point it lower. Now it works well, has never changed position. I have removed it to recharge it several times. All's well that ends well.
This is a great little commuter light, I'd even say I wouldn't hesitate to use as a backup light for mountain bike night-riding. Battery life has been awesome so far, exceeding manufacturer stated run times. It's nice to not need a charging cable, just plug this into a USB. I use it almost daily to ride to work and back. My only major complaint is that the rubber strap is maxed out on my normal-radius road handlebars and I fear it will wear out fairly quickly, the strap is replaceable but definitely an OEM part needed.

- short-ish strap
- strap life (concern, not demonstrated)
- mode-cycling (so many modes can make it annoying to cycle through if you miss one!)
Most of the time day time running light to help me keep safe. It is brought enough to get the attention of drivers.
