I'm still figuring out all the functions on this thing but it just works great. I just wanted it for turn signals for my bike but it is so much more. Not sure on battery life yet cause I haven't had it that long but so far it is still going after about 2 weeks of riding and I ride most every day. Can't recommend this enough.

The rear light is great. I always still need hand signals to make turns.

Just got these and went on 2 rides so far, will update this review for long term, but for now:

Electronics: everything works as advertised. no issue with the battery, the range of the remote is fine, the lights are bright and attention grabbing (a good thing on the road), the lasers can be seen during day time but esp bright after dark. the auto brake light works, sensitivity is so-so but on any fast stops it def. will trigger.

Hardware: this is where I have to deduct one star -- everything works but everything is flimsy. the bike light is entirely plastic, what I thought were heat sinks down below are just artistic expressions. the mounting kits (it has 2, one connects to your seat post, the other directly to the seat stays) are all THIN plastics, and all the supplied screws are PHILIPS. For something that's load bearing, small, and hard to reach, this company decided to use Philips screws over the bike standard hex bolts, which means not only it's hard to reach, easy to strip, it also needs a nut on the other side that's even smaller and even easier to lose. The main light clips onto the mounting bracket via a small locking tab that's no thicker than 1mm -- consider this light has only a 2000 mAh battery capacity, and no power level indicators, you'll have to charge it fairly often (I'm guessing once a week at a minimum -- I ride often), and stress that 1mm piece of plastic repeatedly. Sure it'll be fine the first week, but I have my doubts on the longevity of the whole set up.

It's a great looking light, and from a distance this looks like a grade A product. But upon closer inspection you will know you got what you paid for. for 30 some odd bucks it's a sophisticated bit of kit, only let down by cost saving (poor) decisions, and Chinese "ingenuity". It'll work for now, but I'll come back in a year WHEN this thing fails.

I really liked how easy it was to install this break light onto the back of my bike. I absolutely love the guidelines (either blinky or solid mode) and have gotten so many compliments from other folks in the neighborhood and seen others pick these up and ride with them also.

The battery lasts a very long time. In 400 miles i think ive charged it 4 or 5 times. I just plug it in when i go to sleep on the nights it stops working.

Funny enough ive not used the turn signal function at all.

Update: the company reached out after my initial review and they explained that a lot of the issues I mentioned below have been resolved in their current product. Given their excellent customer service, I'd buy from them again. After a couple weeks of using the light (with black tape over the light sensor) I really like it a lot. Wireless turn signals are a really nice added safety feature.

I was just about to give up on this thing ever working. Like most riders I use my lights during the day for visibility but this product has a sensor built in that turns it off when it's light out. I didn't realize this until after a lot of frustration when I went back and looked through the product photos. I placed a piece of black tape over the sensor and it worked finally. This is an example of a company that clearly doesn't use its own products. Building in a feature like this renders the product useless for the vast majority of riders who primarily bike during the day. It ruins customer experience and defeats the purpose of building in all those other features, which have the potential to make cycling safer (like turn signals, laser lines and automatic brake lights). Now that I've covered that useless sensor with tape I'm happier with the product. I like most of the features and especially like that it's wireless. If I had one more critique for the developer it would be to also make the controller usb rechargeable. Replacing that 2032 battery is a pain.
