This is an excellent health watch, bit a poor smart watch. The SpO2, ECG, BP and HR sensor have been compared to hospital grade machines and gave very close readings. Although, the smart watch aspect is very very very basic. It doesn't do anything else apart from health track. To give you an idea, brightness and choosing from 3 watch faces is the only things you can change. If you want a watch that tells accurate haemodynamics then this is perfect. If you want more then don't buy this watch
ik ben er heel blij mee het heeft wel lang geduurd waarschijnlijk door coved19.Mijn eerst indruk is top mooi scherm hoop dat de rest ook goed werkt Ben hem nu aan het opladen
the smart watch is good
