Very nice light
The light mounted under the seat, easily, and functions as described. Be sure to use the 3rd or 4th light ingoptions, if you’re riding in bright daylight and want the light to remain on. By design, the light sensor will turn it off, if its on the 1st or 2nd lighting options. This is clearly documented within their product instructions.

Good lights
I bought these lights for my road bikes, as a means to put a light on my saddle rails that could be seen over the top of my saddle bag and they work well for that. For times where I have a third bottle these come with a clip-on mount that is part of the strap assembly for mounting on the seatpost, which works well and securely for clipping onto the exterior spots of my saddlebags. Nice visibility to the various light sequences and love the braking warning for extra safety. Battery life is very good, I can get 3-4 30+ mph rides before a charge is needed. Hopefully they prove to be durable long-term.

very well made
I found the taillight to be very well made and high quality. The body is solid aluminum, not plastic. The light threads onto the base so the connections are protected. Light works well and lasts a long time.

Very bright long lasting
Liked that it was easy to install on the post and that the battery lasts a long time. Also liked the automatic on/off feature and the break sensing. Disliked that the manual, like most manuals for products made in China, was difficult to understand.

Easy to mount and out of the way of wheel travel in total compression.
This light is made very well. Simple installation and fits super tight up under seat. I installed up side down to gain more clearance from the tire at full compression. I would recommend on quality and the price.

Great tail light for bicycle.
Great tail light for bicycle. Can be seen from a distance. Also when bicycle slows down light brights to work as a brake warning light. Installs without wiring. The mounting bracket to mount to the seat would not fit my bicycle seat and was useless. But the seat post mount worked great and was easy to install and stays put in place.

Excellent taillight
Such a great little light. Securely mounts out of the way under my seat. In blinking mode it lasts a long time on a charge, several weeks of riding about 5 hrs/week. Charges fast. Love the brake light feature. Only minor complaint is that I wish it would do auto off for motion, but stay on in the daylight.

Nice design and materials; seems like a good buy — time will tell…
Apr 14, 2022:I like the build quality (metal) of the light. I charged it for about an hour before putting it on the bike.The main body of the light is threaded and screws into the socket of your choice. It has an o-ring which should keep water from getting to the USB connection inside while it is in its socket.I installed the seat-mount bracket in about 5 minutes. An allen wrench is included. When attaching the bracket under the seat, I didn’t remove the bracket arms. I only loosened the bracket arms an equal amount on both sides until they fit, then tightened them. Though I didn’t use the post-mount bracket, it seems reasonably durable, and I might adapt it for alternate placement while using the rack on the back of my bike.I’m adding photos that show details I would have found useful, including the English portion of the instruction manual.To adjust the brightness: from OFF, press 4 times to get to CONSTANT (no flash) mode. While in that mode, press and hold the power button. While holding it, the brightness level will cycle between LOW, MEDIUM & HIGH brightness. I’ll include photos of the three levels. It can be done in the other modes, but it’s easier to see the change in CONSTANT MODE.Edit: the photos don’t appear in the order I put them which would have shown the three brightness levels side-by-side.June 18, 2022: In response to a question about a clip-on option, I’m adding a few more photos. The post-mount base can be removed from the silicone/rubber strap and used as a clip.Apr 10, 2023: Purchased 1 year ago and still working well; a very good buy. Jul 23, 2023: Add photos of light mounted on cargo bag.

C’est une excellente petite lumière, éclaire bien, solide, et ça principal qualité elle éclaire plus fort quand on freine. Je me suis gardé une étoile du fait que j’aurais apprécié que cette lumière sur le mode lent, et sur respiration puisse allumé en plein jour.Je la recommande vivement.

Hardware holds the seat frame well. Feels sturdy and is handy for anyone using a dropper seat post when a post mounted light will not work. Update* Replaced with Magicshine Seemee 200
