well i did it. i went to best buy and returned my Fit2. I loved it. The watch interface is clean and neat. The glass is good I havent scratched it yet. Everything else is inaccurate. I can live with inaccurate stair count, but everything else no.
The Bad:
1. Inaccurate distance. No way to manually configure step/stride length.
2. Inaccurate stairs
3. Not all exercise features compute calorie burn via heart rate the same. So calorie burn is not accurate. I did a stationary bike for one hour with multiple pauses, the HR max said 176 and stated i had burned 1000 calories for one hour. No way since i was going so slow.
4. Auto-HR. Misleading because it's not a 24/7 reading rather, it would only read every 10 minutes when you are idle. With some exercises it will turn on.
5. SHealth. No pc based or web based interface. Have to use the phone. Very buggy. Doesn't sync well with any other apps out there. Have to use Withings to Myfitnesspal and barely works.
6. Steps. It doesn't start recording until you walk 11 steps.
7. Support sucks. This thread is the only support I've seen online. A second will be Amazon reviews of the product, however some reviews do not give an honest report of its shortcomings. Not even a Samsung forum for it on Samsung.com.
Anyway, I bought a Garmin Vivoacive HR+. Screen isn't so fancy, but it has 24/7 Heart rate. The band is not replaceable, however it stretches a little and the unit is contoured to the wrist. It is already more comfortable than the Fit2 and much more comfortable than my Fitbit Charge HR. If this doesn't work out, I'll end up with a Fitbit Blaze, at least I already know the UI and its capabilities.
Good luck with you guys keeping the Fit2. With no communication from Samsung acknowledging current problems and future updates I don't intend to keep a potential dud. Most especially the same bugs and problems that's already been brought up before with the Gear, S2, and original Fit.
