Familiarity: I've used it several times
If you're looking for a light to help illuminate your journey, this is not the lamp for you. However, if you're looking for something to alert drivers to your presence, step no further. The Lezyne Femoto Drive Front Light and its multiple settings will alert all drivers, runners, riders, and critters, of your coming. It includes a steady state bulb, a fading setting, a blink setting, and a 70s disco setting.
This light is not to be used to help guide your journey, it is far too weak for that and barley illuminates a few feet past the wheel.
As a complaint, I wish the rubber strap was longer. I have a hybrid with what I assume average diameter handlebars, but I often struggle stretching the strap around the bar. Maybe half an inch longer would be better, but I'll take what I can get.
