Sleepon3 initial review very positive.
Received the Sleepon3 sleep monitoring ring device yesterday. Setup was easy with my iPhone 14. Used the device as directed on my index finger with no issues. I found the ring gave vast sleep data to the iPhone app that I found quite amazing. How accurate the data is for someone else to evaluate. I'm not sure how long the internal battery actually lasts but the charging pad makes recharging effortless. Apple should learn something from this company on recharging devices. So far I'd give this device an "A" grade.
