Review: Better than I expected - 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.
Review: Great product at a reasonable price. - I bought this mainly because I use my iPhone instead of an ant head unit. The app and radar works exactly as advertised. I wear hearing aids which connect to my iPhone via blue tooth. When an approaching car is sensed, I get a couple short beeps through my hearing aids which allows me to check my mirror. The screen on my phone has some graphics showing the approaching vehicle but I find the beeps and mirror checks most helpful. I do mostly group rides and have not noticed false positives from cyclists behind me.

### ⭐⭐⭐⭐ Comparable functionality to a VARIA but with few glitches
*by H***K on October 30, 2023*

Riding with Garmin Varia or Bryton Gardia is game changer due to awareness of surroundings that it provides. One feels safer on the road as you are aware of traffic behind you. I used both with Garmin Edge 830. Similar to Varia 1. Integration with Garmin - automatically connects 2. Visual of traffic approaching is very comparable to Varia 3. Needs space underneath the post; you are mostly likely to lose space for saddle bag. Advantages of Bryton Gardia 1. Affordability: This is 60% of the cost of a Varia which is not small change 2. Mounting: The band and holder is more robust. It is easier to strech around the post 3. Aesthetics: I think the product looks quite attractive with rectangular design and light is bigger. Disadvantages of Bryton Garia 1. Car waiting behind you: When a car is behind you and it is waiting behind you, the car disappears from the radar as if there is no car behind you. It seems radar is unable to see cars if the distance is being maintained between you and the car. 2. False Alert: At times, car gets stuck in your visual in Garmin. This happens about a couple of times on a 90 min ride. Even as car has passed you and there is nothing behind you it will show that there is a car. You know it is a false alert as the car is almost bouncing on the Garmin screen - going forward and going backward 3. I have used it only for 4-5 rides and already had to charge is once. I have not experienced the 17 hr battery life that is on the description. 4. In a 90 min ride, you will see message of 'Radar has been disconnected' on the Garmin. It gets connected within 5-15 seconds...but during that time you are on your own. 5. You need to download the phone app primarily to update software. You can use it while riding as well but with Garmin bike computer, you do not need to use it. I have to test for a few more rides and have enjoyed the awareness that this brings while riding. Update Feb 4th, 2024 Bryton's latest software update seems to have corrected the first two disadvantages. No more false alerts and if a car stalls you can still see it. Fantastic product.
