I tried it twice but I didn't like the way to change the pages. I had to do screen swipes which didn't work well specially when wearing a glove. I prefer in this regard the 520 and the 530. I didn't see that the 820 offered any advantage over the 520. About the same size. It worked well when I didn't try to flip pages or change function.

This is the first GPS bike computer I have owned. I always got by with a speed and cadence pickup to the display on my handlebars. This is so much nicer with so much functionality. It was a "refurbished" unit, but it looks brand new and I haven't had any problems with it. Not looking back....

This garmin has more metrics available than I require . Altitude and percent grade are nice .

Small screen hard to read. Harder to setup than the 810.

Easy to use and install. The app is what makes it a solid 5/5. I like having it connect to my Strava account as well.

A very useful tool for mapping and tracking bike rides and routes.

My wife uses it, it seems like a great product. It does have a problem, however, with cross talk between our HRMs.
