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

Thank you so much

Works as expected. Clear indication of cars approaching from rear, using both audible alerts and visual range. This even includes if it is multiple cars going different speeds.

Very good product

I got these as gifts and it would have been nice to know that these products were previously opened and/or used. Very disappointed and will not be giving them as gifts as intended. Not my style to give open electronics as gifts. Disappointed. This rating is not for the product but for the seller.

Excellent safety device, very accurate and easy to control and setup

This product works as advertised however it drains battery on my garmin edge 520 in about 5 hours. Since I took it for long cycling events it is of no value for me as a radar. Light is very strong. Will return to Amazon

If you ride anywhere other than a densely populated city center like NYC or LA or Chicago... this thing is a real game changer. I have no idea how I rode for some 15 years before getting this. I started using it last summer and I honestly cant believe more people dont rant and rave about them... I dont think it has EVER missed a car behind me. Sure you get some false positives from time to time but NOTHING has ever snuck up on me in thousands of miles of riding now. This is one of the best bike related purchases Ive ever made. BUT, do make sure to keep it on flashing mode, not just solidly ON mode.

Really cool product, works amazingly well, I use it with a Garmin 820. Great for showing other riders and cars!

I would never got out riding without it again. All cyclists should 100% own this.

You cant go wrong with this radar tail light. The only difference between the 510 and this 515 is the Bluetooth feature, which means you can use this one with a cell phone instead of a Garmin (or other brand GPS). I have ridden with others who have the older 510 version and there is no difference in sensitivity, so the 515 doesnt sense a car sooner than the 510. A few times Ive forgotten my Garmin so its good that I can pair my phone with it. I think every rider should own this!
