  • Im changing from 2 stars to 5! Must Replace Product After Only 200 Minutes of Use!
Item Shape: Square Remote
I have had this bike tail light for one year now. Even though I use my bike and the light seldom, the battery on the light lasts a very long time, which is great, because it does not detach from the bike easily and therefore, in order for me to charge it, I must either unscrew it to remove from bike or take my charging cable with extension cord to the bike and device. I have only had to charge it 3 times in one year, awesome, except on the third time it would not recharge. I have used it approximately 200 minutes in total over the course of 1 year and it already needs replacing. I keep my bike indoors at all times it’s not in use. Pros: works great, easy installation, sturdy parts, bright lights, great functions, works seamless with blinker, maintains a very long charge. Cons: The devices battery only works for approximately 200 minutes, leaving the product useless, charging is not as easy as it should be, device is quite expensive for the limited time it works. I have contacted the manufacturer with this issue and will update this review with the outcome. My recommendation: Prior to knowing how the manufacturer resolves the issue: waste of money, buy a more reputable brand. After the manufacturer attempts to remedy the issue: TBC. 2/27/2024 - UPDATE So, I never heard from the manufacturer, which is disappointing. However, it turns out it was operator error! I decided to try and charge it with a different cable, one that wasn’t as powerful, and it works! It charged and it works great just like it did before so I’m changing my review from 2 stars to 5 stars. Based on the fact that customer service never responded, I could easily remove one star, but considering there was no problem to begin with, I will give them the benefit of the doubt. This is a a great product! And, a life saver, if you’re a night rider, like me. ... show more

  • Nice safety feature for a bike
Item Shape: Square Remote
Great multifunctional rear light. Turn indicator, brake light, horn, and one hell of an alarm in case anyone tries to steal your ride. Well worth the money

  • Good functionality, fairly priced
Item Shape: Oval Remote
The lighting is reasonably bright, perfect size and style, all parts arrived well-packaged, charged well, fairly priced. The remote functions, light modes, and alarm, all work well. *The remote initially stopped initially, but is working well after successfully resetting/pairing.

  • Works While Charging
Item Shape: Oval Remote
Good product, bright and with many functions. My main purpose in leaving this review is to let prospective buyers know that IT DOES FUNCTION WHILE CHARGING. I ran a USB C cable from my ebike battery (using a Step Down Converter) to it and it does in fact operate while 'charging'. I had questioned this previously and was told that it did not - It does. ... show more

  • Excellent Tail light
Item Shape: Square Remote
Excellent brake light ! So many different settings and even comes with left and right turn signal and hazard light. Tail light brake light setting is great. Tail light stays on and when hitting your hand break. The brake light comes on when braking like a motorcycle or a car.

  • Bad design with alarm buttons.
Item Shape: Square Remote
Good idea in theory but poor execution. I really wanted to like this bike light with turn signals and alarm but the alarm function ruined it. The alarm button would get bumped and the alarm would go off and it wouldn’t always shut off when the button was pushed again. The last straw was when the alarm armed itself again and went off and the remote had fallen off the holder so I had this ear bleeding alarm going off while searching for the controller. I would not recommended unless they made this alarm feature with a switch rather than a button or removed it all together. Everything else worked great and I used the other features regularly. I will be buying a basic bike light now and throwing this one away. ... show more
