I've used this ring oximeter for years. Generally I wear it at night. It gives a very accurate measurement of O2 throughout out the night, as well as a useful summary of how much time was spent in various O2 ranges and how many times O2 drops. It also has various alarm settings which i disable. The last thing i want is to be woken at night when my O2 drops, but it may be useful to some people. One thing i like a lot is that it gives the time when you tap it. I wake up frequently at night an like to know what time it is without looking at a clock that sheds light all night long. The app on the phone is easy to use. I lost my original ring on a recent trip and just bought another, which is why I write this review now

It appears to have lasted about 7 months.For the first 7 months, it worked very well. The O2 and pulse rate info was very valuable, and the O2 warnings were super helpful. The unit was easy to use and comfortable.Starting a couple of days ago, it started malfunctioning. First, instead of a single recording from the whole night, it would break the night into multiple segments, or not record chunks of time. Then it started triggering very noisy Device Offline alerts from the app (even though I have those turned off). Last night those warnings were every few minutes, and I took the O2 ring off. It was properly charged and Bluetooth was fine (for other devices).Not at all a good value for 7 months of service. :-(Update: As mysteriously as the Device Offline alerts started, they stopped after a few days, and the ring is working fine. So I am adjusting my rating.

These O2 rings are accurate. They keep a continuous record of oxygenation, heart rate, and movement all night (or all day). The battery has lasted me over 12 hours. It probably lasts longer than that but I haven’t worn it longer than 12 hrs.The app gives you the ability to view and print a full page, detailed report covering the entire night. The report is in color, so it is very easy to read. I recommended it to my 82 yr old brother, and his report indicated low SpO2 at night. His Dr ordered a sleep study (pending) based on the report.

It seems like it can't suddenly read pulse/O2 and it vibrates and shows -- on the screen. After a few seconds the pulse and O2 starts showing again, but it starts as a new session. I see another reviewer had the same problem. When it does this it wakes me up. Sometimes in does it 3 or 4 times a night. I've only used it 4 nights and it has woken me two out of the four nights.I am sending it back and will try another one and hopefully it will work better. I've worn it during the day to ensure that it wasn't losing good contact and it's not. It just seems not to be able to sense my pulse/O2 which causes it to restart.Update:I sent it back a got a replacement. It worked fine for a few days and then I got the reset again. I contacted support and they stated that if the sensor has pressure applied to it, that it will cause it to reset. They also suggested I do a Factory Reset from the app, which I did.I used it for a few days ensuring that I kept it away from the pillow and it worked okay for a few weeks. Then suddenly last night it started resetting. It did it about five times and I ended with the last four resets recorded and lost most of the nights sleep. I know that it wasn't toughing anything since I was awake.I did another Factory Reset and I see if it does it again tonight or the next few days. I only have until November 12th to see if this thing will keep acting up and waking me up. If it does, it's going back for good.Useless to have a device that resets so often that it wakes you up and doesn't record you full night of sleep and only has four sessions that are each about 30 minutes.
