I have one, purchased in mid-April and have had it crash 3 times, so can be annoying. If it happens again I will explore returning and switching to a Garmin 520.
My 810 crashed the first day I owned it, and I lost data within a few days.
I returned it and got a factory refurbished Edge 800 which is reliable if I split long courses/rides into multiple pieces and combine them later. Not doing that it crashed 140 miles into a ride and lost everything back to when I rebooted it at mile 20.
Garmin firmware is horrible and getting less reliable as they add features so I bought a Wahoo ELEMNT before the 810, but returned it when it didn't accurately record or display power and turn-by-turn directions weren't shipping in Q1.
Currently (there's a beta with turn-by-turn for ridewithgps) it doesn't do navigation at the same level as the six year old Edge 500 which gives you audible + pop-up alerts for turns or other points of interest (WATER) and distance to the next (one on the map screen, three on the cue sheet) course points. Instead it just gives you a chevron trail and alerts when you make a wrong turn, which means you need an eyeball glued to the screen to follow it.
The ELEMNT also has map problems. Minor roads like those used for cycling are invisible when zoomed out, and unlike the map-equipped Garmins there's no way to pan the maps to see where roads go. The ELEMNT is also missing street names.
