I have used Garmin products for 20+ years and have been quite satisfied. Among the products I currently use are the Edge 1030 Plus, UT800 light, HRM, and Venu 2 watch -- all great products. I also have the original Varia "Rearview Radar", also great. However, I had always hoped Garmin would incorporate a camera into the Varia unit, so when announced I immediately bought it *knowing* that I could rely on high quality from Garmin. Sadly, this product leaves much to be desired: yes, the tail light and radar work just as well as the previous units, but the camera has no image stabilization and the software's file management is awful. First, the default is to create 90-second files! That can be adjusted, but apparently not if the file is created automatically by radar. Given that you may have hundreds of files from a ride, one might hope they could be easily viewed and copied. Nope -- you must select and transfer them one at a time, and much more slowly than expected. Currently, the only option for me was to pull the SD card and plug it directly into a computer. I can only hope Garmin will address the SW issues (including adding stabilization) and remove the bad taste & disappointment I've had from this purchase.
The radar works just like the other varias. The camera works just fine as an incident camera. Do not buy this if you want an action cam. Do buy this if you are tired of running a Varia + Cycliq Fly6 side-by-side in a custom 3d printed mount that keeps breaking.
This essentially combines the Fly6 and the Varia together into one package. If you're using this as an incident camera, you really shouldn't need to get footage off of it very often, so the software side doesn't bother me at all.
I have a RTL510. When I saw this product announced, I immediately ordered one. After seeing the DCRainmaker review, I changed my mind, as the video review and transfer is so slow and to be unworkable.
I did receive the RCT715 but sent it back. There are three issues.
1> It is bulky and heavy. It's about 1.5 times the size of the RTL510/515 (thicker and taller) and about twice as heavy.
2> It uses a different mount. This is a problem for me, since I already own the RTL510 and planned to use it as a backup on longer (60+ mile) rides when the main light ran out of battery.
3> I want to be able to retrieve video to make police reports about dangerous drivers. Based on the DCRainmaker review, I'm not sure I'm willing to put in the hours necessary to find and transfer the right video.
For the money, I think the RTL515 is a better investment.
Please take this for what it's worth. I don't think this is a good upgrade from the RTL series, but it still might be a good investment if you are starting from scratch and really want a radar/camera combo.
