  • Very high quality. Easy to use.
Item Shape: Circle
The first thing I noticed was the high quality of its construction. Very easy to mount to most common bike seats with several lighting options. The brake light feature is nice also. Just unscrew the light from the mount to recharge it. I highly recommend it.

  • The only taillight you should have
Item Shape: Circle
First, quality is just insane, very good, It comes with two straps, one metal and one rubber, It's a type c charger, very convenient, I can use any cable at home, it also comes with a USBC cable. Light, let me tell you about the technology built-in in this taillight, This light can differentiate between night and day. Which means it can save light if you're riding during the day and turn on automatically during the night. It has a built and sensor so when you break it illuminates like a breaking lights in a car. It turns off automatically after 30 seconds and as soon as you move it turns on again. Just incredible little light As for that durability, I haven't used it that much yet. I'll let you know later So far I'm really impressed. PS. This is not a paid review. I bought it with my money. ... show more

  • Great Design
Item Shape: Circle
This is a neat little light! The brightness isn’t so much that it’d be particularly noticeable at range in the daytime, but it’s more than enough for night. I’ll he clear; The brightness isn’t special, but as a tradeoff, you get solid battery life. The different light functions are also pretty neat, and being able to cycle through them with a single button is nice. It’s simple, and I have no doubt that it’s built well enough to last a good long while. It’s also quite small and light, but doesn’t feel cheap. I can imagine it working quite well on a road bike just as well as a moped. Good stuff! ... show more

Just got it so can't speak to longevity, but it's light weight, small, but very bright

  • Works as advertised, recommended.
Item Shape: Circle
Honestly you're better off with a kinetic break light than a regular one. And this one does a great job, never failed, long battery life, bright, waterproof, multiple settings. Great all around. I put about 5k miles a year on all bikes. All my commuter and road bikes have this light.

  • Best rear light out there!!
Item Shape: Circle
I am running 3 of these lights on my mtn, gravel and fat tire bike. Easy to install and mounting bracket is durable, battery stays charged for many weeks, excellent value and really bright. The stop light feature works unbelievable. Highly recommend, you can’t go wrong with this light.

  • Durable, easy to install, great battery life
Item Shape: Circle
This light has exceeded all my expectations, especially for the low price. - It was easy to install. - Inconspicuous under under the bike seat which makes it less likely to be stolen. I live in an urban area and have had many lights stolen. I've been leaving this on my bike even when locking it in a public place, and it's still there. - Long battery life thanks to the auto-off feature, it probably lasts a month on a charge, and I bike 4-5 days a week. - The "brake light" feature is nice when biking in a group with someone close behind you. ... show more
