Garmin 010-02376-00 Varia RTL515, Cycling Rearview Radar with Tail Light, Visual and Audible Alerts for Vehicles Up to 153 Yards Away

Ive used almost every day now for 60 days. GREAT Garmin product I feel 100x safer using this!

Works great and charges fast

After several uses, I kept asking myself... Why didnt I get this radar much earlier? Cynics saying a mirror would do the job that the Varia does isnt completely wrong Except Varia does much more than a mirror. Firstly the Audible beeps to warn me of approaching car more than 150meters back, without taking my eyes off the road. Trying spotting a car on a small bicycle mirror that far back while keeping 100% focus on road ahead. Secondly, mirror users are partly replying on sound. The unit picks up another cyclist riding overtaking at higher relative speed to avoid collision or wheel touch.

Love this! Use it every time I ride

I was originally skeptical about this device due to the price. It took only a couple of rides to become a dependable addition to road riding safety. The biggest difference it makes is at high speeds, when you cant hear incoming traffic. You can visually have a quick check on the unit. Also, its ability to mark several incoming vehicles is handy instead of relying on sound to gauge how many cars are about to pass. On the down side I get sometimes a disconnection message when in fact the light is still operational. Would buy again in a heartbeat.

I waffled on this purchase for a long time. It seems that near $200 US is just plain expensive for technology that has been around for a very long time. But....there is basically no competition and if you use Garmin devices this will enhance your riding experience tremendously. If they could sell this at half of the price every road cyclist would have one.

Really useful out on the road. Would recommend.

Works flawlessly. Replaces rear view mirror for me. Spots all vehicles behind, peace of mind. So far so good after first ride.

Had to knock off one star for price, but this thing is awesome.

This is one of the best bike accessory I have ever bought. I do a lot of road biking and I feel very secure with this radar device. It synchs well with my Wahoo Elemnt (although Im told that there are more functions if it is synching to a Garmin device). It shows cars quite a ways a way and the color coding of a cars speed is also helpful. It is most useful on the open road as opposed to in town since there are so many cars in town I always assume there is one behind me anyway and as a consequence there are lots of warning beeps, but these are a minor inconvenience compare to my riding outside of town. I have not noticed any false positives or false negatives which is consistent with many reviews I have read and with the experience of other cycling friends. It is not cheap but in my view the added safety it provides is well worth the price.
