Review on Wellue SleepU Wrist Sleep O2 Monitor - Wearable Finger Sensor with Smart Notifications, Shareable APP & PC Reports by Nikita Sweet

I bought the O2 Wellue SleepU Wrist Sleep Monitor a week ago. I already have a Wellue O2Ring and have been using it extensively for the past 5 months. I have a lung condition and need supplemental oxygen for every activity. The most important information to protect my health is my oxygen saturation. The user-set low O2 saturation alarm on the O2 Wrist Sleep Monitor Wellue SleepU alerts me to a change in my behavior before I have an exacerbation: unwanted and dangerous symptoms (cough, shortness of breath, etc.) that I have been using up until now have Wellue SleepU Wrist Sleep O2 Monitor for over 14 hours every day on a single charge. I use two devices to monitor oxygen saturation 24 hours a day, 7 days a week - one charges while I wear the other. These wearables allow me to control my own specific health data, warn me before my O2 level is too low and encourage me to take positive action for my health. If I want, I can see the graphics in the app. I believe that over time such wearable medical devices will bring significant advances in improving the health of those of us who use them. Pros: long battery life; low O2 alerts; the application allows you to view the data in detail; Finger movement does not affect accuracy; less obtrusive on the finger than the O2 ring; Easy hand washing while wearing. Cons: No heart rate alert; The reading is about 1% higher than my other oximeters. Full Disclosure: Wellue has agreed to reimburse me for the Wellue SleepU Wrist Sleep O2 Monitor. This did not affect my rating in any way.
