Heart rate is accurate enough at lower/resting heart rates but is terribly inaccurate during a higher intensity workout. On the same workout, an ECG (Polar H10) shows my average HR at 152 BPM but this watch shows my average HR at 108 BPM. I’ve tried wearing the watch tighter, looser, top of the wrist, back of the wrist–but it’s still consistently inaccurate.
Blood Pressure monitor is inaccurate as well, about 20 points off a cuff measurement. I’m not expecting complete accuracy, a 20+ point offset is too much.
Pedometer registers steps even when I am just laying on my bed.
When starting a walk workout from the phone, the average pace is recorded, but the slowest and fastest pace are blank. When starting a walk from the app, the slowest and fastest pace are recorded, but the average pace and heart rate data are blank. The GPS data is also inaccurate, I was walking 4 laps, but it only location tracked 1 quarater of 1 of the laps.
The built-in music speaker is nice to have but the speaker peaks easily and it’s on the bottom of the watch so you end up covering the speaker up when wearing normally and muffling the sound. Also not being able to reduce the volume from the watch is annoying.
The sleep tracker showed me as sleeping until 11am when I was awake working (sitting down) since 6am.
The touch screen goes off accidentally and often, “wrist-calling” recent contacts on my phone.
Receiving calls on the phone seemed to work properly.
The software on the watch is lacking. It’s the same white-labeled software that runs in many watches around this price point yet each of these watch brands have their own white labeled app that only works for their hardware. The software is buggy with reproduceable crashes. The brightness setting would revert and not save, the watch would randomly reset your customized watch face, the watch would not convert to imperial units and clicking the temperature on the app would crash it. They fixed the imperial units and temperature crash on 1/7/23, but it required resetting the app, and losing data from that day.
Battery life was barely 2 days.
Overall, the watch was cheap in all aspects. I can’t really blame anyone other than myself for hoping otherwise. It’s an interesting toy at best but cannot be relied on for workouts.
