  • Excellent value for a long-lasting, bright, back bike light!
Great light. I purchased almost 2 months ago, now, and I have yet to charge it. I use it almost every night because my bike is my primary mode of transportation. There is a charge percent indicator on the light, and it currently is at 56%. It seemed to stay at 100% for days, then 99% for days, and so forth. So, excellent functionality. I like the light pattern options. It was pretty easy to mount; I just use the stretchy attachments. Easy to strap on and take off, easily adjusted. It seems small, but the light is sufficiently bright. Excellent value for the $9.99 that it was. I'm extremely happy with my purchase. ... show more

  • Fantastic, bright and super light weight too
This is a fantastic product and solution to your quest for a light weight, long lasting (charge) safety light. This light blinks bright and steady while riding, then when you hit the breaks and come to a stop it gets brighter and steady, similar to a vehicle brake light. Sit for a few minutes and it turns itself off, start moving again and it turns itself on. Really bright too especially in this Florida sunshine - you can see it clearly from a distance. All that - and cheap too! ... show more

  • Nice quality little unit
Very bright, small and light. Lots of flash choices. I like the quick flicker setting. One thing that kind of bothers me is that it shuts off if you stand still for very long - but fires up again when you start moving. I would prefer it just stay on. The LED display does look cool at night.

  • Great ligt
Giving it a 4 start only because it is not bright enough when in "normal" mode. The battery indication also seems not not work properly as it is always showing 100%. It is easy to install and it is durable. I like how it detects inactivity and goes to sleep.

  • BRIGHT AND AMAZING BATTERY
EXCELLENT PRODUCT. BRIGHT AND BATTERY LASTS FOREVER AND THE PERCENTAGE METER IS EASY TO READ. LOVE IT.

  • So far so good
Not as bright as some other taillights I’ve had but I’m really happy with it and I really like the motion detection function that acts as a brake light. I’ve been using it on my commutes (about 10 miles, 30-45 mins each way plus trips for errands here and there on the way home) for a couple weeks and the battery is only down to 66%, so it seems to hold a charge well. The battery level indicator is also a nice touch. Overall this has had very good performance and I would recommend this. ... show more

  • Don't buy it, it won't last
Really bright light with a lot of different modes. The problem is with the rubber mounting. It doesn't last. The light comes out of the rubber mount and you can't get it in again. Total junk, do not buy this light for your bike. Terrible just Terrible. Get the Keywell with different sizes and it has a great battery and is way brighter. This light is no good ... show more
