Review on USB Rechargeable Bike Lights Front and Back - 1200 Lumen 6400mAh Set with Wide Angle View, Free Tail Light Included - Easy to Install Bicycle Rear Lights for Road and Mountain Cycling - Safety Flashlight Headlight by Scott Tompkins

The mount is pretty solid, much better than others I've had. Bright as it gets. The only downside is there is a bolt sticking out of the bracket that makes contact with what it's attached to so it scratched my stems where I installed it. I fixed it easily, you can just wrap tape around the screw. It no longer scratches and now seems to hold up better wherever it's installed. If I charge the battery on a Sunday, it lasts until Thursday evening at full brightness. So almost a whole week. My drive home in the dark takes about 40 minutes and I often go outside at night as well. so almost 4 hours in real life. Pretty good battery life if you ask me. A little smaller than advertised, but I'm still happy with it. I'd shake it a bit, but set it up at the right angle, screw it all the way in to lock it in place, and it's significantly quieter. It has a few issues but the brightness is great, the battery life is great, the beam itself is wide enough, it's a great light.
