It's better than I'd dared hope for my particular needs. I don't know anything about the seatpost attachment components, as the option I needed/use is the "belt clip" style attachment that's part of the light itself. I clip it to a webbing loop on the back/rear of my under-seat bag, and from that location, it gives an excellent view to traffic. I don't routinely ride after dark, but wanted this light for increased safety for daylight riding and into dusk on occasion. Especially for the modest price and light weight, I'm really impressed with how bright this tail-light is, and the several different types of "flashing" light options in addition to solid "on".
This thing is bright! Even in the lowest setting. Could be too much when riding with a group of someone was right behind, other than that you will definitely be seen in the dead of night!
Super easy to use, super bright, good battery life. Not much more you can ask for from a bike light. I find the built-in clip to be useful for attaching to my rack if I'm not using the seat post mount.
I chose this light because it has a hook mount, which I use to attach it to my helmet strap. The hook is very secure, it's never come loose once in over a year of riding. Even though it's small and light, it puts out a lot of light. I just bought a 2nd for my commute bike, where it mounts on the rack. I've had it on for many hours during long rides, it has never stopped working.
It is difficult to find lights that are rated very good, especially quality and design. This light is the exception, the brightness, ease of attachment, battery life and ease of use make for a top choice. The only negative is the silicone USB port cover may be a little dificult to close, but I am on to it now. Overall I highly recommend this light !
i like it very much , i wish the battery would last longer
Very bright-- to the point of possibly annoying others. Hinged mount allows you to focus light downward if you think it's too distracting. I found a second mount to switch between two bikes. Lightweight and good price.
Muti functions hi brightness
Bought this as a spare. Current unit is bright, easy to install, easy enough to remove for re-charging and easy to operate. Use as a daytime rear flashing light.
Almost a year of ownership and this light is amazing. It is BRIGHT and the combinations of lighting patterns will be sure to get the attention of approaching drivers. Excellent light - I am so glad I bought this and use it when I am on the road.
Working early morning and needing a good tail light. This one gives everything I need.
Perfect light output for the size. Mount is good and easy to use. The built-in clip works great with jersey pockets and the rear of saddle bags. Charges fast. Lasts several 1.5 hour rides before re-charging when using flashing mode.
Purchased to use on bike helmets (my wife and I). Have had numerous comments from car drivers on how visible we are and how much they appreciate the additional visibility. Terrific product. Btw, we also use garmin varia.
This thing will definitely let anyone within 2 miles know that you are in the road. USB C charging is convient and the dual mounting is handy.
