Delivered quickly. Priced better (less than half) than comparable Garmin unit. I like the quarter turn mount and it feels solid. It paired with my Bryton S800 head unit seamlessly and it displays a little graph that is intuitive and helpful at a quick glance. The audible beeps are also helpful and easy to decipher. It has been very accurate with detecting vehicles in daylight, dusk and night rides. Never had it 'miss' a vehicle yet but have had a few 'false positive' detections that usually resolve quickly. Gives great confidence of approaching vehicles. It shows how many vehicles and their relative distance to me and each other. Closing speed and 'all clear' indicated by differing color of graph. Doesn't seem to false detect cyclists as vehicles. It did take me a few rides to notice that vehicles that are moving at the same speed as me won't necessarily be detected or continue to be tracked if they initially are detected, those may 'clear' with a green indication and beep. They do 're-acquire' if they begin to close distance though, which all makes sense but took me getting used to.Riding with buddies that have the very similar Garmin Varia, the functionality seems nearly identical. They also get occasional false positives though not necessarily at the same moments. The light is bright and has several modes. Battery life seems to be as advertised which is very good and MUCH better than the Garmin my buddies use. It does shorten the battery life of my head unit slightly when in use, maybe 10% or so. My S800 has an almost 25-hour batt life with my particular paired devices (HR monitor, speed/cadence, power meter) so I barely notice to be fair. If I unpair the radar, I assume this would not happen but have not tried that as I'm looking for more than just a taillight obviously.11/21/2024 update: after a firmware update the unit started constantly disconnected and reconnected from my head unit as I was riding. After a couple of days a firmware update for my head unit became available and that update resolved the issue. Not sure how that may have affected use with Garmin or Wahoo though, but something to be aware of.
