It's light, simple, bright, and easy to attach.
The charging is easy: Pop off the cap with the attached elastic bands on to the light's tip that has the small rubber flasher control button. Plug the light into your PC's USB port, or a USB charger that plugs into an outlet, or into a USB port on a charger/surge protector combo device. This information is not on the lean, snug package and the Knog bot on their website provided a cluster of redundant, frustrating messages that were not helpful. Knog is based in Australia. Their goofy bot is the only CS resource for several hours for Northern Hemisphere bikers. G'night, Mateys.
I have ridden with a tail light for years, but this is a bit nicer. It's not what I would call a critical piece of equipment, but it's nice to know when a car is coming up - particularly when riding double file with a friend, or when doing intervals and there isn't much or any shoulder. I turned off the sound alert cause it's annoying. The visual on the side of my wahoo is sufficient. I like that I can see multiple cars approaching. The sale price as Garmin has brought in a new version made it more compelling. The old micro USB isn't great, but it's not a dealbreaker either. I'm not seeing any false positives or false negatives so far. If a car slows down to match your speed before passing, that's the only time where you might not see them registered.
The lights themselves are great, nice and bright with different settings/blink patterns to match the conditions! The main problem is the strap for the rear light, it's flimsy and does not have one side permanently fixed to the body of the light. Within a week of buying two light sets, one rear strap broke and the other was lost while off the bike being charged. Lezyne sells replacement straps for ~$5, including different lengths, so I bought multiple.
These have been around for awhile so no new developments, but dang do they work great. As a cyclist for more than one decade, my ear radar detectors work damn good. This device works better. Often times in cycling, value gets a bit lost, but this honestly feels like a good value for money. Being able to see how many cars are behind me and how fast they are coming is confidence inspiring and helpful. I love that it actively flashes when it detects them as well. I hear them adjust behind me as soon as they see it. It's not expensive and it works flawlessly, hard to find a fault. Except one.......Garmin your micro usb port is woefully out of date and irritating. Just stop it. Give me USBC. 100% of micro usb devices in my house are Garmin. No excuses.
