My Experience with Gardia R300
I used Gardia for about 200-300 km together with Garmin Varia. I placed Gardia on the seatpost and the Varia on my helmet to avoid signal interference.
I connected both to different bike computers (Karoo 2 and Edge 830) to watch how quickly they would detect vehicles.

Both radars detect them at basically the same time. However, while shooting a video review, I noticed that Gardia is not as accurate at detecting multiple cars. I tested this by pointing it at a highway with more traffic.

Anyway, Gardia never missed any cars. It only gave a false positive (showed a non-existent car) a few times per ride. I don’t consider that a major problem. These false positives were more frequent than on Varia RTL515 but less frequent than on the Magene L508.

But what about battery life? I tested the battery life in day-flash mode, which is probably the mode most people will use the radar in.

After the first 4-hour ride, it looked like it could reach 16 hours (the remaining capacity was about 80%). Unfortunately, the battery started to drain faster and faster.

All in all, I got down to about 11 hours and 40 minutes. Compared to the supposed 17 hours, this was quite disappointing.

It’s worth adding that I tested the radar in temperatures around 41°F (5°C). So lower temperatures may have affected the battery life. On the other hand, the 2-year-old Varia lasted about 9 and a half hours in similar conditions.

Battery life aside, I like the design of the Gardia, its app, and I am happy with the mount. It’s very solid and doesn’t need to be adjusted in any way while riding, even after dice.

I will continue using Gardia to catch some bits here and there. However, the value you get for your money is adequate. The Gardia suffers most from real battery life that is much shorter than claimed.

кратко Bryton Gardia R300 работает нормально, батарейка не такая крутая как обещали, чуть лучше гармина

И крепление хвалит

Апгрейда не особо стоит, видимо. 20% батарейки и usb-c. Но как первый радар - надо брать
