Great light great price

I really like this little light. It’s bright enough that cars will see it while I’m riding twisty country roads. It’s plastic where it makes contact with your seat post. This initially made me worry that it would scratch up my carbon post, but no signs of wear yet. It also stays put and doesn’t twist around the post. I will say that it’s a little difficult to get it on and off around a 27.2 seat post.

Pros: small, lightweight Cons: battery life weak - 2 hours at best in flashing mode. Not really acceptable for longer rides

My new favourite light, need to be seen

Needs to be updated to usb-c. Micro usb is old school and not practical anymore

Everything good with this light

Great, small size tail light that can mount at top of seat post. Only drawback is small size means it has a smaller battery, so need to recharge after every few rides.

Clip is no good on a seat bag. Lost on first ride. Great as a helmet or seat post light.

Very happy with this small light that don't need you to screw something on your bike. Really easy to mount, battery lives forever. I'm riding around 3-4 time a week in the morning, in flashing mode I charge once in 2-3 weeks. People who wrote that they lose this light in first ride - probably not mounter it correctly.

Small, powerful, and convenient!
