Wellue responded quickly to my email regarding questions I had about calibration because of different measurements simultaneously from 2 Sleepue devices. They suggested doing all measurements on left hand thumb for accurate readings and gave me a 10% discount on ring SpO2 HR which is much more stable during activity.
