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

Excelente compra, si bien no te libra de un accidente pero si te hace más consiente del entorno, este radar te permite identificar cuando un vehículo viene aprox a 700mts y da tiempo suficiente para reaccionar. Me ha servido mucho y me siento más seguro al rodar en bicicleta.

Use it on my foldable bike , sometimes riding on roads which Is useful safety features

Accurately showing cars coming from behind while biking.

This is a very cool device/light. I think they are absolutely worth getting. While you shouldnt rely on it 100%, what Ive found is that its quite accurate (Ive only had it miss a car once, and that was in a residential neighborhood with the car maybe only going 10-15mph, so ???). What this means is that I find that I leverage it not just for knowing when cars are behind me, but when they are not. This lets you say ride further away from the shoulder when you need to, or if you happen to be on a road where cars are rare and youre say riding no hands down the middle of the lane (eating, putting jacket on, whatever), you can be alerted if you have to adjust, etc.

my only complaint will be the same as the new one. the rubber band mount tends to rotate after being on rough roads making the radar not pointing properly.

I am a amazed at how much this product enhances my riding experience. All those times where you need to look behind but its tricky because you are going fast downhill or concentrating on grinding in a climb are eliminated. One glance and you can see if there is a car coming up behind you. Huge safety boon. I highly recommend it!

Excelente duración de batería , gran iluminación y presencia . Integración simple y muy seguro

Very accurate and provides high visibility to the motorists coming towards you.

Yes, it works. So far, no false alarms (other than when riding in a group, of course). Download the app, stick an earbud into your non-traffic side ear, youll get pinged every time a car comes behind you.

For what its designed for, it does work. My biggest problem with it is that the sound alerts are played through the phone and the app keeps the phone awake. I would like to have an option for the sound to come through Bluetooth.
