I had a friend tell me that they could see this light - and me, which is what it's all about - a mile away on a long, sweeping downhill. It's bright! I'd say it's "Impossible to miss" but I lack that hubris in these days of distracted drivers.

On full brightness this light is super-bright!! Brighter than any other light I have seen or used (which includes the Bontrager lights and Garmin lights). If you are looking for a light to use during the day, this is it. Battery life at full brightness using the blink mode only lasts me for two rides, though (rides average about 40-50 miles each). I don't like that I must remove the light to charge it.

GREAT!

Fabulous light. Battery lasts forever. Super bright. My boyfriend who is a long-term road biker is jealous of my sweet taillight! He has several different models and they never last even half as long as this bad boy.

Great rear light...VERY bright, easy attachment to seat post, streamlined appearance !!

Bright

best one so far.. long lasting bike lights worth $$

The light is amazing. The best one for day use I ever had. The duration of the battery is very good and the blinking options are very suitable for day and night. The only thing to take care is the charger port cover. You need to keep very well closed, and use a strong rubber to keep tight (seatpost and rubber cover.

This is my favorite rear light for long distance riding. In the low setting, it can easily last 6 hours. It is lightweight, durable and stays where you put it despite rough terrain.

Great light. Very bright with multiple options.
