Wellue WearO2 Ring
Just purchased a Wellue WearO2 Ring, what a piece of junk how can a company sell such an inaccurate device that’s close to being dangerous to use. Keeps failing to read and when it does telling me sats are in low 90s and pulse rate mid 50s. Appears to be a random number generator rather than a serious measuring device. Money wasted. From other devices pulse is low to mid 80s. No other method to check sats. UPDATE Still think accuracy not great but some problem solved after talking to friend told to give finger a good clean with wipe to remove grease before wearing , they had similiar problems and seems to have helped.
