This light is great for shorter rides. The battery last about 1.1/2 hours on a full charge in the lowest power, flashing, mode. The annoyance happens when the rubber strap on the mount breaks. At that point you have a $40 useless light.

It doesn’t last longer than 3-5h. It is sleek and light so if you’re riding a shorter ride then it’s perfect. For endurance rides, I’d say this might not be the best light

It's simply a great light - nice design and fit size.

Great to keep in your bag - can be used front or back

These were half price in the sale so bought two. A simple button press switches between a front (white) or rear (red) light. Various settings from static to flashing. Easy to charge. The rubber band to attach to handlebars or to the frame at the rear was easy and secure and they’re small and light enough to stick in your pocket

innovative way to mount on holder. not a flashlight but good for visibility

Not really bright enough for a night ride on MTB tracks.

Got one of these as a gift several months ago and have used it as a tail light every day since. Need to charge it maybe once per week, which is pretty good. It is bright, visible, and easy to use. And very durable. Today's ride was very wet, so when I got home, I decided to spray the muck off my bike. Took the light off so it would not get drenched by the hose. Put it in my jersey pocket. Of course, I forgot it was there and threw the jersey in the wash. Later, when I realized my (ironic) error, I went and retrieved it from the (now clean) jersey, which was hanging up to dry. And, much to my surprise, the light still works just fine. Brilliant little device. I recommend it.

Great lights. Very powerful and compact. I fit them onto my helmet well. However, they are a bit difficult to take off.

I am very satisfied with this. I don't do night time. Just wanted a daytime running light so was a bit concerned about only 100 lumens as you can also get 200 lumens in the same style light. I find it perfectly fine and extremely impressed with the battery life. On low flash it lasts my I think it was 10 rides for me. Highly recommend.

It’s perfect

Hard to fault, an excellent light!

Excellent light extremely bright easy to recharge and disconnect if leaving bike in a public place for a period of time. Highly recommended

Great bright light. Secure fit behind my s-works seat post so nice and compact.

Definitely recommended for the great illumination, I got also one of these for tail light and works awesome. Great lights for the day to day bike rides. If you are planning to ride at night in low visibility or nature (with no street lights) I would recommend getting also a helmet light for extra support or get two for the front handle bar. Heads up, the bike cables might get in the light projection so just some cable management required.

The perfect light for the everyday rider. Bright, easy and you can move it from front to back simply depending on weather conditions to be seen where you need to be seen. Very very fast shipping. I am not happy with my LBS (Specialized) so.ordering online is so convenient and less frustrating

This light is a must have. Its super easy to install, bright, and easy to recharge. This is so nice without have cords or a bunch of attachments. Charge and install - works and not hard to figure out...and safety is key. Bright for the early morning or late rides.
