- It works, but not exactly - the blood pressure greatly underestimates. Other watches with the SmartHealth program have the function of adjusting and calibrating the smart watch sensors, after which the watch displays accurate readings! This has been repeatedly tested and verified with medical devices. The Wearfit pro program cannot calibrate smartwatch sensors, so the readings are not accurate - you just have to take into account the errors and "in your mind add" to the readings in order to represent: "What is the real pressure and other readings." The microphone and speaker work well.
- The Smart X8 Ultra Series 8 with Wearfit pro software does not allow you to adjust and calibrate readings to provide accurate, reliable readings.
