Had a traffic accident in college . . always worried about being seen on the road when on my bicycle. This light works as expected, no, better. Tall vertical red light that cannot be missed. Nice size and plenty bright. Easy to attach, and stays in place. Easy to remove as well. Modes are easy to manage, really like the slow blink. Good throw towards the back and when vertical easy to spot from the side. It is the side view that I really value when in traffic, day or night. So I use it all the time. Glad I chose this one, will see if holds up under use, but for now I can say it is still going on the first two and a half hour charge. Also appears well protected from the weather.
