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

Absolutely, the best taillight, ever! It is awesome with sensing cars but DOGS, too!!! THIS IS THE BEST MONEY IVE SPENT ON CYCLING TECHNOLOGY ✔️Great battery life! After 90 miles, I recharge

Works perfect (despite reviews of busy streets...will show multiple cars in sonar path very accurately). Love it.

I love this thing.

The Varia model tested was the RVR315 without the taillight (with the light it’s model RTL515).

Garmin Varia is like a seat belt for your car, can’t ride them without them. A must have.

Great product!!!

Works well as advertised...even for rear approaching cycles.

I will not go out on the road without this. Works great with my Garmin 530

Definitely recommend this if you ride frequently on the road which any amount of traffic and have a Garmin bike computer to combo with. It will occasionally pick up other cyclings behind you as vehicles, but it’s better safe than sorry. It has never missed a incoming vehicle from behind. This really helps you focus more on your ride and what’s in front of you. Great battery life. There have been days where I forget to charge it overnight and just by using my cars usb charge and a 30-45 minute drive time to the meet up spot, it was powered throughout my ~3.5 hr ride.

This device is a gotta-have for riding in light traffic. Has saved my bacon more than once.
