Radar

It is very accurate and can be seen very well from a distance, and the battery lasts a long time.

Nach meinen Garmin Varia RTL515 suchte ich etwas mit USB C.
So bin ich auf Seemee R300 gelandet, angeschaut, gekauft montiert.
Die Kopplung an Hammerhead Karoo 2 und 3 kein Problem.

Das Gerät funktioniert fast Fehlerfrei, ab und an Erkennt er Fahrzeuge die einfach nicht vorhanden sind.

Wenn ein Fahrzeug hinter dir mit der selben Geschwindigkeit wie du fährst, erkennt das System das Fahrzeug nicht mehr!

Bei Minus Temperaturen, hält der Akku max 4 Stunden!

Schade das man nicht von Blinklicht auf statisch umgestellt werden kann!

Sonst ist das Gerät top

Genial! Excelente luz para dia y noche. Si la combinas con tu ciclocomputador ruedas muy seguro. Su patrón de parpadeo cambia cuando un coche se acerca haciéndola mas fácil de ver para los conductores.

Long life battery, easy to pair with gps, high range of detection, can see up to 4-5 cars in a row. My first radar, i'm very satisfied. And also a fair price. Perfect.

Easy to use, strong backlight and the radar signal is perfect for the traffic behind which I can track on the watch. Nice workmanship. The battery life is also adequate.

La luz es muy potente incluso en un día soleado , me da mucha seguridad rodar con este radar , tengo que reconocer que en mas de una vez si no fuera por el radar no me abría dado cuenta del auto que tenía detrás, mas con la tendencia de autos eléctricos que emiten casi nada de sonido.

It offers great value for money

It offers great value for money. I really love the clean, well-thought-out, and high-quality design, as well as the hardware build. However, the app malfunctions for me quite often; it freezes or loses connection to the light, and I have to pair them all over again. It would be great if they could fix the false alerts on the radar light. Unfortunately, I lost the light on a train. So I only had it for a short time, but while I had it, it was really great to use.

the bike seat mount is broke jus on my second ride

the bike seat mount is broke jus on my second ride. i guess the radar light is too heavy for the mount. obviously not practical.

I used it just once and I was not able to to set it in a vertical position therefore I can't fully evaluate it. Sometimes it gave the proximity with a car sometimes not, but it could depend on the position where I place it.

Reliable. Bright. Great for nighttime or early morning or anytime bike rides. Like different flashing modes.

Light works well, connects to Garmin 840 easily. Don’t like the mounting should have a rigid mount for under seat.

I live outside a small town
So on the hinterland country roads it can track following vehicles.
Great job
