indeed, won't put my faith 100% into the watch. But I started to monitor so that I can have base mark to work from when I do get the mouthpiece to compare to with.Blood oxygen should not really go below 95%.
Dunno about those sensors' accuracy though.
But I must say I have calibrated and compared the blood measure vs my blood pressure machine and most of the time it is about 99.8% similar.
