This bike tail light works just as expected. It was very easy to install on my mini bike. I'm happy that it provides adequate lighting for others on the road to see me. The remote control works okay, but it's nothing to write home about. I just use it for the basic function of signalling and that's it. Overall, I'm happy with my purchase.

This tail light is decent quality. The remote turn signal pad works well. The light has a bunch of modes including an auto brake light. It senses vibration & lack of vibration to turn the brake light on. I'm not sure it worked too well with my escooter. Since there's not much vibration. I didn't really use that mode. I just wanted to use the turn signals. I'd like to see a company make something like this but have front & rear turn signals. I'm not sure the auto break light is a big win with me. But it's not a bad idea. It just needs to work better for an Escooter.

This is a great addition to have on your bike or e-bike. The feature that Attracted me to this product was the sensory of breaking. As a driver, I’m not able to validate it functionality on a consistent level, but it seems to work and recognize breaking pretty well.

I was intrigued by this bike light because of it's unique wireless control and functionality. Avoiding wires saves a lot of complication. This advanced technology allows the tail light to detect motion and breaking without the need for external electronic or mechanical sensors. It has two auto modes to conserve energy and one manual mode. In auto mode, it detects normal vibrations from the wheels turning on the ground. It has a number of energy saving features. It detects ambient light and turns off the tail light when it is not needed. During low ambient light, it will keep the light on (flashing or "breathing") as long as you are moving and it will keep the light on for 30 seconds after stopping. When you break, it senses the unique vibrations associated with breaking and turns on the break light, or you can manually turn on the break light manually with the remote control. The remote includes left and right turn signals. To conserve energy, the device turns off the signal after a short period of time. I can highly recommend this product. With all of its nice features, it is not without a need for some design and user manual improvements.1) The current manual is very difficult to understand. It needs to be re-written. Pairing the light with the remote is well explained online. To pair, press and hold the power button on the light until it flashes. Then quickly press any button on the remote while the light is flashing. If you wait until the light stops flashing before pressing a remote button, the pairing with not happen and you will need to do it again. The light can be mounted either directly to the seat, or to the seat post, using the appropriate mounting adapter.2) The current energy saving features for turning off the tail light keeps the lights on for 30 seconds. This is probably OK for some times, but 30 seconds is likely short if you want to stop and look around, or to talk with someone for more than 30 seconds. It would be better if the grace period were 1-2 minutes instead.3) The turn signals turn off automatically after a about 15 seconds to save energy. That may be OK for many turns, but it may prove to be a problem if you must wait for an extended period time in traffic, as the turn signal will turn off. Since you cannot see when it turns off, you need to remember to turn it on again after about 15 seconds when needed. Far better would be to allow the user to turn the turn signal off when desired by pressing the same turn signal button again.4) Since the remote battery cannot be charged, it presumably uses a "button"/disk battery. It would be good to include in the manual information about that battery and replacing the battery. The manual needs to include better instructions on how to orient the light when mounting so that left is left and right is right. One must experiment to figure it out. It turns out that the tail light needs to oriented so that the power button is on the left.While the light could use some design improvements, it is still a great advancement for biking.

There are a few things I like about this item, but more that I don't care for. I like that it has an emergency flasher; I ride on the road with vehicles a lot and I want this on all the time; however, it isn't as bright as other lights I've added and is difficult to see in sunlight. I like that it has turn signals, but I don't like that I can't tell if they are still going since I can't count the 15 seconds they stay on while I'm riding; if they had the remote blink for 15 seconds too, it would make it easier to tell. The turn signals, like the emergency flashing, are difficult to see in sunlight. I like having a remote switch on my handlebars to control the device, but I had difficulty pairing it with the flasher (it took 4 attempts) and if you kill the battery, you have to pair it again. The remote switch should also have rubber on the back of it; even with the strap as tight as I can get it, it still moves when I press a button. The instructions SUCK. They are printed much too small and are confusing. I'm still not sure all of the ways it works after reading it three times with a magnifying glass.Update: I went for a ride this morning and the one thing I liked about this didn't work. I tried using the remote to turn on the flashers and they wouldn't engage. The turn signals worked, but not the emergency flashing - junk.
