I really liked the light - long run time and bright, especially in daytime mode. The mount is another story. The tabs to secure the light to the mounting point are very small and don't engage forcefully. I got a few months usage out of mine but it eventually fell off on a ride and was lost.
I've had the PDW USB Danger Zone for several years. It's the best rear light I've ever used. This one? A major disappointment. The lights are SO much dimmer than any other tail lights that I have. It's a much less noticeable light. The attachment mechanism angel can't be adjusted, so on 2 out of 3 of my bikes the light is angled too far towards the ground. Thinking I need to replace this with something better ASAP.
This list didn't attach well to the light attachment that I bought for it. I returned d it and bought a different light.
I have many daytime rear lights as I really believe in there effectiveness .
This is the only one that I have that lasts 8 hrs and is still as bright as when I started.
It poorly fits to my saddlebag
The light is not half as good as advertised (particularly compared to the Blackburn Central 50)
More than once, I had to use something to press the Onchange button deep enough to activate.
There are much better products for the money
