Review: Awesome Bike lights!! - These things are awesome! I have 6 of these lights, 2 on back of bike, 2 on back of helmet and two facing forward on my handlebars zip tied to the mirror mount. They are very easy to mount and have multiple ways to mount though I prefer the silicone strap. To me they are worth the cost. So far the battery life has been good and since you can adjust the setting of the lights via the app you can go for battery efficient or more brightness. I highly suggest getting the remote and pairing them for turn signals.
Review: Fantastic for my use. Maybe not for yours. - Love these with a few caveats. The form factor is nice, they are bright enough, blinker function works very well, app is alright. The battery life kinda sucks and the wireless charging is inconvenient. Just use usb c and id be so much happier. Charging from dead takes a while and they don’t give any feedback about their state of charge. For my cargo bike I cannot find a better light with blinker functionality. If you have a regular bike and don’t need the blinker function I’d probably look elsewhere.

### ⭐⭐⭐⭐⭐ Awesome set of lights
*by J***S on June 25, 2023*

So these are awesome. They work with my Lumos matrix helmet. I like the fact I can turn off the helmet and all the lights turn on. I wish that was the same for turning them on. You have to turn each one on individually. These were easy to install and get going. Be sure to read everything because there are features that are available that are not easily found. I wish there was some sort of plastic mount that could house two of these on the front or rear of the bike as a pair. Including a charger of some sort would also be beneficial. I am still waiting to see how much battery life I will get out of these. I am enjoying them and find that they are made exceptionally well. The magnetic mounts are super strong!
