I compared the cardiac pulsation measured with a chest strap "Wahoo Fitness' to one or two beats ready measurements are identical (the Wahoo being more reactive during measurements).
The device is given for accuracy:
SPO2: +/- 2% from 80% and 99 +/- 3% 70 to 79% by cons below 70% precision is not defined.
Heart rate: +/- 2% of 30 to 250 beats per minute.
