Great product easy to use
Small screen hard to read. Harder to setup than the 810.
Fantastic! Touch screen. Easy to use and keep more data and stats than my 520. Best part? Less expensive than the 520 and does more!
I have owned a couple of units (510, 520, 820, 830). 820 is the worst in terms of battery life. I love the 830 but will never ask anyone to buy 820.
Greatest upgrade to my bike.
Easy to set up if you've had a previous version.... nice up grade
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.
Cracked my first one in a wreck and bought the same version to replace
Use 820 for road. Great screen view, easy to setup, easy to use.
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.
