Great SPO2, slow to get heartrate, SPO2 algorithm doesn't work well below 90%

I've tested this while sleeping and during the day. I wanted a good SPO2 monitor, and heartrate monitor during exercise. If I push my heartrate up to 160-170 range the watch never figures it out. I tested this at the same time with another HR monitor. I do some Wim Hof style breath holding, and the algorithm never recovers if you hold long enough to lower saturation below %90. Lastly, when I get up in the middle of the night, I get false positive apneas from the app. It would be nice if the watch knew to mark part of the SPO2 data as ambulating. That would help eliminate false positives. I recorded times I got up and was awake so I could tell that there were false positives. I do like the product overall. I hope you find the information helpful.

My step count and blood pressure

What can I say but I am truly happy on my purchase of H4-V12 as it is serving all my needs. And to have ongoing health updates is so comforting.

Very dissatisfied.

Not impressed, notifications doesn't work. You get what you pay for. Lacks good Bluetooth connectivity. Can't recommend this watch.
