It's super easy to use. Just put it on your thumb and it turns on and starts recording. So far I can use it all night, sometimes 9 hours or so, and it still has a little under half battery left. If you have it on over 10 hours it will start a new recording as each one is limited to 10 hours, but it does it automatically so you don't loose any data. The screen goes off after about 30 seconds and you can turn it on (for another 30 seconds) by tapping the round circle on the screen. This lets me easily check if I wake up in the middle of the night.
I especially like the graphs that their software produces. The oxygen level and heart rate are vertically lined up so it's easy to see what each was doing at a particular time. I wish the lines/bars on the "movement/activity" graph were a little larger so you could see movement better, but they are good enough. One graph shows all night on a single line with blocks of 1 hour (up to 10 hours) so you get a big picture view. Then it's broken into another graph that spans over 4 pages or so and are in 1-minute blocks displayed at 4-second intervals. For me, I can easily see when I go into and out of Afib. The device uploads data to PC quickly and I especially like that I can convert an entire graph/report to PDF with one click. This makes it super easy to keep permanent records. With my PDF program I can have two windows (with different nights) showing to compare.
I also have Sleep Apnea, so this allows me to monitor my oxygen levels, something I've wanted to do for a while. This lets me know that my CPAP is working.
Now for the ring: It is comfortable and seems to work well. You can have a live display of your readings on your phone which is very convenient if you cannot be looking at your hands. I compared the SP02 function against a regular finger pulseOx and seemed to get good readings. In fact, it seems to be more accurate than my other finger pulse ox device. The resting heart rate readings are accurate, but elevated readings, such as during exercise are not very accurate. During exercise I had three devices comparing my heart rate. The readings for two of them were 143 and 145, which was about what I expected. The O2 ring only gave a reading of 105. The ring works well for resting heart rate but not so well for elevated heart rates.
The ring has a black plastic screen with numbers that are way too small. I hope they increase the display size in future versions. There is a setting for normal and "always on". In regular mode the screen stays on for a few seconds and turns off automatically whenever you tap the button on the face of the ring. I wish there was another option for 30 seconds or 1 minute. Sometimes I find myself having to tap the button multiple times when I am staring at the screen. Not a big deal though. The band is a silicone, and fits different sized fingers with ease and comfort.
Overall, I think if you need this to track your resting or sleep data, it works great. If you want it for exercise, this may not work for you.
After contacting wellvue, they promptly shipped a new replacement ring. Company was very quick to respond to my initial complaint, and shipped a new replacement. The ring is a great tool and provides peace of mind. I would and have recommended it to friends.

One thing that caught me off guard though is that if you have this on you while walking, you can get sudden low oxygen readings and warnings being triggered. Looking into this some more I found out that one must stay still and keep the hand still while taking a measurement. Just something to be aware of so you don't go into a mini panic attack like I did 😅
The Apple Watch that I have will detect movement and warn me to keep my hands still. Once I started doing this then I saw the blood oxygen levels going back to normal again.
