I bought these pedals to get power number while I ride my gravel bike. I have Shimano SPD cleats and these work just fine with them. So far I've ridden my gravel bike with these pedals a total of 6 rides in 1. 5months. Three of those rides were on gravel and the other three were just riding around town. These pedals connected very quickly to my Garmin 1030 and they stay connected - no drops or connection issues so far after stopping and starting mid-ride. I'm not a huge fan of the app but luckily you only need to use that during initial setup and whenever you want to update firmware which I do not plan to do more than once every quarter. I haven't had to charge them yet after 8-9 hours of riding on them. I wouldn't def recommend these to folks who don't have the budget to purchase the dual sides pedals.
I ride a race bike on semi-rural roads in Northern California and use a both flashing taillight and small rear view mirror attached to my glasses. Occasionally oncoming cars will enter my lane to pass and it�s clear they either don�t see me or don�t care that I�m there. This light addresses the former drivers. It is quite bright even in sunlight. It is also small and virtually weightless. My mirror saved my life once, so I am aware that there are.both homicidal as well as distracted drivers out there. This light helps minimize the threat from the latter.
I've been road riding with one of these for close to 20,000 miles and it has been nearly flawless. I ride a mix of city streets, county highways, and desert single lane roads. The radar gives me a much better sense of surrounding traffic than would a combination of hearing and head-turning. False-positives are rare and seem to happen when turning right at intersections. Missed cars are extremely rare, but the RTL515 is still not a substitute for looking over your shoulder when changing lanes or passing parked vehicles.
I'm using the RTL515 with a Garmin 530 Edge unit. The dot and colored band on the side of the screen works well and is easy to see in your periphery vision or a quick glance down. It's not like you're reading a number or deciphering data to see that a car is gaining on you. It's simple and safe.
My RTL515 is a few years old, but as far as I can tell it still uses a USB Micro cable. This is literally my only gripe. USB-C is easier to use and should last longer.
After observing my friend using his Varia radar light, I had him hook my Garmin Edge to his light and got to experience first hand as long as I stayed close to him. My wife asked what I wanted for Christmas and the deal was done. Installed easily but then had to learn a few things as the pictograph directions are sketchy. Lucky my buddy knows all about it. I especially enjoy that if one is not paying close attention it will chime and let you know another bike is coming up faster than you are.
