This is a breakthrough product. For 2 years I've been trying to *accurately* and *simply* monitor my O2 each night so that I can work my way off a CPAP machine. Here's why almost nothing works: 1. Apple watch: don't measure continuously and is expensive 2. Other fitness watches: generally don't measure continuously if at all, plus accuracy issues 3. Oura ring: more accurate than watches, still not continuous, and now the most expensive of all thanks to their required subscription Enter the Wellue ring. More accurate, more thorough and less costly than any of the ones above. I can actually measure my O2 drops with confidence and get daily measurement of my progress. Incredible value.

Great product. I've been diagnosed with pretty severe obstructive sleep apnea. I got this product to help optimize my cpap treatment and learn habits about how to make sure the treatment is working the best it can. I learned about how my sleeping position effected my o2 levels and I found a way to sleep to improve my treatment results. The data collection is great. 10/10 would recommend.

Seems to be accurate. Needs a longer battery life in ring. Info on the ring is hard to read, especially for older folks.

Works well to record pulse & O2 overnight. It is a very useful tool to supplement my fitbit & sleep monitor app on my phone.
