Review on Blackburn Click USB Front and Rear Light: Illuminate Your Ride Safely by Ronald Noel

Pretty bright and easy to use. Works well but I have a few small gripes: - The strap is not permanently attached to the device and can be lost very easily - Turning off the light while holding the front is a bit awkward and doesn't always work on the device First try - this Rubber pad protecting USB port doesn't fit snugly in socket, meaning water and sand can get into the port if you're not careful - while the light effectively gets you seen from the side, as intended, it also means that this being the case there is a lot of glare in your eyes which reduces your night vision.
