551 hours logged. Wearing it almost exclusively 24/7. No hick-ups, just some minor bugs, like HR zones being overwritten with version upgrades. No connectivity issues (but only using it with a HR strap).
Plenty of activities logged, such as bike, indoors bike, mountain bike, run, trail, treadmill, elliptical, stair machine, indoors rowing, strength (gym), XC skiing, alpine skiing, skating and some hiking. I also do structured workouts.
Firstbeat algorithms seems reasonable. My reported running VO2max has been at 1-5 points below my lab tested value, and that seems ok, as outdoors running adds some effort. Reported altitude when alpine skiing is lagging. Current pace when running is perhaps not as smooth as wanted.
Had to replace the first watch strap after 7 months (a bit disappointed, it started to crack near the clasp). Added a leather strap for use when not training.
Have compared it to my previous Suunto Ambit 3, and have difficulties seeing any differencies on the GPS tracks. Possibly the Suunto is better on trail under dense trees. But comparing the tracks to my even earlier Polar RS800CX with the G3 external GPS, the F5 is far better.
Happy with the battery capacity. I get 6-8 days out of it with my use (GPS almost every day). The Suunto gave me as little as 60-70% of specified capacity after a year (and it did have some hick-ups).
Wouldn't mind even better battery capacity, and GPS tracking. I am also wishing for improvements in OHR. It seems to be ok for daily tracking, but not for logged activities.
I appreciate the buttons rather than touch screen (much preferred actually). I also prefer the screen, compared to the Apple watch (I just recently compared the screen of my F5 with my old Polar RS800... what a difference!)
Looking forward to another 551 hours (or more). With hopes of no bugs, broken OHR sensor, straps, deteriorating battery, screen, etc (as have been reported here). And of course the health to be able to enjoy the hours.
