Garmin’s latest RearVue 820 is technically impressive, but it isn’t the straightforward RTL515 replacement many riders wanted. In this video, I make the case for a Varia RTL525: USB-C charging, longer battery life, a better-positioned power button and the same proven radar behaviour, mount and US$199 price that made the RTL515 the benchmark.

You forgot one important feature… A lanyard slot. I have lost two!
Or just improve the 820 based on user feedback
Yes Please! I’d buy that one in an instant and recommend it to everyone I know!
TrainingPeaks Virtual (now part of Garmin) welcomes the TPV Grand Tour at the end of September. It’s a free-to-ride stage-race. And they do offer prizes, including the Garmin Varia RTL 515 !
I seem to be having trouble playing your YouTube videos in particular. The only one that seems to be working is the most recent Zwift video. The rest go straight to error. I also tried other channels to make sure it wasn’t just on my end. Problem occurs both via your site and directly on YouTube.
Actually, I have now tried older videos on other channels, and am receiving the same error. Most recent videos are playing. Older videos are erroring. Must be a problem with my device or YouTube. Sorry for the false alarm.
