Apnea Management Device
I been using Wellue O2 Ring for past 3 years or so. I have been struggling to understand my sleep pattern and Sp O2 during my sleep which I could get only from Wellue O2 Ring. I have tried out all that I could find and I have no hesitation in saying Wellue O2 Ring is surely the best. They are very reliable and after sales service is extremely efficient. It has helped me manage my Sleep Apnea by changing my sleep positions and follow it changes in my ring. I am very happy with the ring.
