MagicshineSEEMEE R300 Smart Radar Taillight(Return to Product Page)

The light performed exactly as described. Very simple to set up on my bike and pair with my Garmin. So far the battery life has not disappointed and I like being alerted to approaching cars/bikes.

I now have the brightest taillight in our riding group, though I'd like to set it lower and then brighten or flash when the radar is triggered (and maybe I haven't found that setting). The radar function works really well and integrates with my Garmin 1040 perfectly. You get an audible notification from the Garmin then a dot (or dots for multiple cars) that rises up the side of the display signifying as the car approaches. When paired, the taillight powers on and off automatically with the Garmin. There are frequent "false positives", but they are easily discernable as the cars don't advance. And I am OK with that and don't callout to the group until the car advances halfway up the screen (30-50 yards) when its more actionable and I pretty certain that its not a false positive. Of course, sometimes a car pulls off once it's been detected. Battery life is good, seemingly lasting 15+ hours on my setting. I'm in a habit, however, to charge when I charge my Garmin. A little bulkier than the Garmin Vario but much, much brighter and much cheaper.

The lighting of the Magicshine SEEMEE R300 is very good; the flashing light is visible from a considerable distance, which effectively helps alert drivers and improves road safety. As for the radar, I consider its overall performance to be good, although it has a margin of error, as it occasionally triggers false vehicle alerts and also detects cars traveling in the opposite lane.

I absolutely love this light. Would recommend it to anyone
