Typical garmin, tons of functionality, took time to tailor it to my in ride needs. Way more data/ options than my previous wahoo system.

So bad I returned it.

Used a few times and returned it.
Battery not holding a charge. I would charge after the ride and next time it was 80-something percent. The following time it went from 100% to 65% between rides.
Solar charging is nearly useless. Gained less than 10 minutes on a 4 hour ride.

Love the edge 840 solar

I love this. I can see the route and it even tells me when a climb is coming. With the solar it has tons of battery life. I’ve ridden 200 miles and it’s only at 45% battery.

I loved my Garmin 840 and haven't had trouble for 3 years. But now it will never sync up with my phone. I have reset the device disconnected and reconnected the Garmin from the phone and no luck.

The computer works great but the connection to Garmin Connect to download activities is horrible
