I removed the rubber strap and plastic clip then treaded a velcro strip in place. Now I can strap the light to my ankle to provide biomotion, an established way to help motorists see cyclists. My only complaint is that on steady mode, it only lasts a few hours.
Like the size, charging cable and simplicity.
I changed the rubber clip out for a piece of velcro, and now it works great for my helmet for additional visibility. I really like the USB charging capability, and it lasts 2-3 commutes on blink mode easily (6 hours)
Easy to attach to bike with included strap. Easy to remove and charge. For a small and light weight provides substantial lumens (and two settings) for safe riding. You will not be disappointed...
