This light is easy to install on your bike, and easy to detach from the bracket so it doesn't get stolen when my bike is locked outside overnight. The one minor problem is that it often turns itself on when I'm carrying it around in my backpack--you need to pack it to make sure the button doesn't accidentally get bumped. 5 stars

I fail this unit due to it overpriced and non green N batterys which are not avable in recycable style 2 stars

These guys are great. They make good solid products at an affordable price and they still find room to give back 25% of what they make to the cycling community.

This light is pretty bright for it's size. I've used it rain or shine for quite some time without any problems. This is part of my night riding equipment and clothing which includes Illuminite leg and arm warmers Performance illumiNITE Leg Warmers, and Down Low Glow Side Visibility lights Down Low Glow Lighting Kit - Two Tubes -Ice(blue) 5 stars

This is a pretty good back blinkey. It's easy to mount and very visible for it's size. 4 stars

It'a a little bit small, and difficult to open to put the battery for the first time, but once it's done it works fine. 3 stars
