LYNWO M9 0.96inch Heart Rate Blood Oxygen bluetooth Smart Bracelet
US$26.94 US$44.99

Q: I just received this watch today. It des not seem to read my heart rate,nor measure the spO2 nor BP. The detector is flashing green on the back of the watch so I know is working. Is there a problem for the detector to read values if the skin is dark color?
