APACE USB Rechargeable Bike Tail Light Super Bright 100 Lumens Bicycle Mountain Bike Tail Light LED Light Clip On Easily to Serve as Red Rear Light for Optimal Cycling Safety

Seems to work so far (2 weeks and haven't had to plug it in to charge it). I just turn it on and let it blink its default blinking pattern. When winter comes I'll experiment with the brighter, more strobe-like blinking patterns.

Mounting: I am a very petite female, which means I have a very small frame bicycle. So I can't mount a light to the seat tube (saddle bag takes that entire space), and potentially am also unable to clip a tail light (if it even has a clip) to the saddle bag (quite a few lights hang far enough down that they occasionally hit the tire on bumps). So a tail light primarily designed to mount to the seat stays is ideal (for me). And can also be easily swapped between bikes whether they have a saddle bag or rear rack or neither. (If you want a light to clip to a saddle bag, this wouldn't be a good option, but should work fine on the seat post).Reliability: I have found that very, very, very few tail lights reliably stay on for the entirety of a ride. (They don't run out of battery, just randomly turn off, possibly due to something momentarily disconnecting during bumps). I've used this light for at least 5 rides now, and it has still been on at the end of every ride I've used it on. (In comparison, Cygo and Ceco's seat stay tail lights both failed miserably here, and were promptly returned to Amazon).Battery life: I've used this light on multiple rides without recharging it, and it didn't die (which isn't true of all my taillights) so I don't have to worry about whether I'm able to or remember to charge it between rides (useful, particularly, if riding multiple days on a camping trip). I haven't fully tested the battery life, so can't speak to exact amount.Brightness: The high setting is pretty bright - not the brightest, but far from being weak. The lower setting seems to be an ~perfect compromise between not blinding other riders and not being ridiculously weak. (I found Cygo's version to be too bright on the high setting for group riding, and pathetically weak on the lower setting).I would definitely recommend this light for anyone not looking for a clip-on tail light. And I would definitely strongly recommend it over its competing name brand lights

Light stopped working or charging after one use

Merece la pena. Da muchísima luz con 5 posiciones diferentes y batería de buena duración. 3 segundos apretando el botón para encender y apagar, y se enciende en el último modo programado. Muy fácil instalación con el sistema de gomas y aguanta perfecto el trajín de la montaña. Lo unico que para cargar tienes que desmontarlo pero es un segundo

They didn’t fit on our bikes so now we have no back light.👎🏻🤦🏼‍♂️😡😢😤
