love the options, but not the battery life. Many times this thing dies on me after just 1 hour and 15 minutes. It override the low light switch all the time witch drains the battery even faster. for this much money I demand better. I use a garmin head unit and radar tail light so this seemed like a no brainer, but I am going back to my cyclic head light. It's half the price and does everything this garmin does for twice as long. sorry garmin, you missed the mark on this one.
Finally picked up a radar taillight with the outgoing Varia RTL515 on discount and I have to say, I've appreciated the radar/light more than I thought I would. I haven't used it in the dark yet, so I cannot speak to the effectiveness of the tail light, but the radar function has made me wonder how I survived so long without one. I assume no bike radar is 100% perfect when it comes to picking up cars, but in several weeks of usage, this model has been probably 99% accurate. Get yourself one before they're all gone!
Interfaces with radar/light unit, easy on/off mounting (came with numerous mounting options). Good battery life. Like the feature ability to track fellow riders over busy courses (e.g RAGBRAI type events).
I was updating my old Garmin Edge 530 which served me faithfully for 6 years or so. I don't replace gear that often so this was a big change for me. My first impressions after 200 miles or so indoors and out. The unboxing process was seamless; I unboxed it and synched it using house wi-fi. Everything from my old unit worked seamlessly and the process was fast. Initially I noticed my phone would interfere with the Wahoo Kickr core signal. Solution was to connect phone last. Same thing happened using a Garmin Varia. I just needed to connect ap on phone after getting 840 set up. Otherwise system is a great upgrade. I actually was on the fence about touchscreen but after using it for a couple months I've gotten used to it and love it. Overall great experience and I'm happy I didn't spring for the extra solar charging unit.
