Review by Low Country Biker
I have bee using a Garmin 510 for at least six years. After a recent software update I noticed this radar unit listed in the menu. Upon a little research I found that with the update this unit was compatible with older Garmin units. I purchased this rear light/ radar unit and have been using it for the past month. I've been impressed with its performance and ease of use. I ride mostly on paved county/ farm type roads and average about 700 miles month. The unit warns me when traffic appears about 400 ft behind and graphically shows the progression toward me. I have found it very helpful when I have to merge into a traffic lane. I always look before moving but this shows the gaps in traffic and lets me know when to look back. Good product

This product has made my rides a lot less stressful. I love getting a warning that a car is approaching before I can hear it. When I'm flying down a hill it's comforting to glance down at my Wahoo Element Roam, and see a nice green line, letting me know that the road is all mine. I would have bought one sooner had I soon it was compatible with my Wahoo device. I was proud to say goodbye to the little mirror on my sunglasses. This is much better, and I like a little cooler!!

I use this with my new Garmin 1030 Plus. I feel much better now when turning left. Even with a mirror, I like the radar for giving me the added security!

I have had both the radar only and the radar plus light. The 515 turns my light and radar on which allows me to skip two activations in the back. A small plus. What makes it more convenient than the 315 is the 515 battery life is significantly longer. Less removals for charging. I know, I'm lazy. Other than that, they are both fine and I use now use the 515 all the time.

Wish I had bought this sooner than I did! Held off for years using helmet mounted mirror! That was dumb! This is so much safer...works perfectly with my Edge 830! Only challenge I had was where to mount it as am also using a camera on seat post. Saw where some folks had mounted to seat bag using a home-made bracket! I did this and it works well - movement of the bag does not seem to bother it! Got caught in rain storm which didn't stop it from working but killed the camera! Only suggestion to Garmin is to add provsion for a safety cord as they have on the Edge units!
Review by Rusty Bottoms
The Varia radar is seriously awesome. My buddy had one and was able to call out whenever a car was coming up behind us on a ride. I quickly bought one shortly thereafter and it is a necessary item whenever I'm out on the road. The peace of mind that it gives while descending at speed and having a warning when a car comes up behind me is worth the price alone. I pair it with my Garmin Fenix watch and it gives me an alert, love it.

excellent battery life
great app for battery and warning of approaching vehicles
Garmin computer syncs seamlessly with the light, and you as a rider can get prepared for passing cars with plenty of warning, ~ 1 mile on a straight road, less on curvy roads. Love it! feel naked riding without one now!
I think this is a must have safety item unfortunately these days, with so many distracted drivers and so many large vehicles that approach us way too close for comfort.

What a great piece of gear. The radar brings your situational awareness to the next level.
Review by BKane
The Varia RTL515 has immediately become indispensable for me. I ride mostly country roads and have never been able to get used to a helmet mirror, so the Varia is great. It picks up vehicles at the same time as my riding partners with mirrors. The battery life is fantastic - no problem for 100+ mile rides. Garmin undersells what I think is a great feature - the reactive-blink tail light. I think drivers intuit that increasing blinking to mean you know they're there, and they are less apt to brush you with their side view mirror. The only feature/flaw that I see as a negative is that any vehicle that appears on the radar then matches your speed disappears! Once you realize that, you can adjust your perceptions accordingly, but this characteristic of the radar could be in all caps in the manual. Overall, not inexpensive but worth every penny.

This product to me is a game changer. I bought this because with the pandemic I was mainly riding alone and felt more vulnerable to cars than in a group of 20 riders. This tells you without looking that a car is coming from about 1 1/2 football fields away (I think actually 143 meters). You can see it approaching you and how fast. I know if I happen to be riding side by side to mover over or if by myself to move as far right as I can. Even if there are things in the road like a hole or debris I know if I can just go right around it or if I need to slow down because there is a car. The brightness of the flashing rear light increases as does the frequency when it detects a car. There is also an audible tone if you want and colors of the approaching car to indicate how fast it is approaching. I see people riding with mirrors but this if far superior. I think at $199 it is the deal of the century. Seems more than worth it to avoid getting hit by a car. Battery life is great. Syncs perfectly every time to my Garmin. Easily can be transferred from bike to bike. Takes about 30 seconds.
Review by Rob Hill
It only takes one ride to realize how valuable this is. It works extremely well. It does not get fooled and give false alarms very often. However, if you are riding on a trail that parallels a street, it will rightfully pick up that traffic. If you make a 90 degree turn, the cars passing on the street you just turned off of, will briefly trigger the radar. When you do get an alarm (a very distinct beep) there is plenty of time to react and being able to track its progress is fantastic. If there are multiple cars approaching you will see multiple dots on the screen. It does very well on twisty roads as well. It detects cars approaching around corners sometimes before you can see them. My only word of caution is to always charge it up before every ride. Not that it doesn't have a good battery but It takes a lot of power to do all this and a real bummer if it runs out during a ride.

Wish I bought one sooner, as it's a brilliant product. Picks up vehicles way sooner than my mirror or my ears, and graphically shows how many vehicles, and closing speed. And it paired instantly with my Garmin computer. A huge advancement in safety, and other than being a little heavy it's a must-have for any road biker or commuter.
Review by Mick
Im 75 with bad hearing and cant wear my hearing aids because of the wind noise. I ride in Spearfish Canyon and there is a lot of traffic at times and loging trucks. It works great and if the are several vehicles behind me it will show each one on the led lights.
My son bought it for me on Fathers Day several year ago and I been using it ever since
I highly recommend it.

The varia radar is may be the best (and most important) piece of kit I have bought! While I continue to use a mirror to see WHAT is coming up behind me, getting the warning on my head unit prior has been indispensable. It allows me more time to focus on the road ahead, only having to glance in the mirror AFTER I get the warning from the radar. Riding on the road has been a night and day difference since I installed this on my bike!
Review by Fourflys
Never thought I needed an additional piece of tech on my bike until I bought an older, used Varia.. after using that for a while, decided I never wanted to ride without one and decided to upgrade to the current model with a better battery and light. Pairs instantly with my Wahoo Bolt v2.
Review by redrandy
I already had one, so I know how great this thing is. I also use a mirror, but have to say this is one of the best tech things I've ever bought starting with my first odometer that mounted down by the dropout and only recorded mileage....(yeah, I'm that old and have been riding that long).
I do turn off the alert sound though as anytime I'm near town and heavy traffic it's way annoying....otherwise zero complaints.
Review by MR. JEFE
4 Stars because of it being kinda pricey.
This is my 2nd one. 1st one broke off on a rough trail (crappy 3d printed mount I made) Not fault of device at all!!
I ride alot of dirt roads and this gives me a heads up when wind/dirt noise makes cars behind hard to hear.

Be seen day or night and be aware of anything approaching from behind. I never ride without it. A must for every cyclists.
