Wellue O2Ring Pulse Oximter, Bluetooth SPO2 Blood Oxygen Saturation Monitor - Wearable O2 Ring Sensor with Vibration Reminder, Free APP & PC Report, Rechargeable

This unit is very comfortable to wear even through the night. It flawlessly connects to blue tooth. You can save PDF or CVS reports if needed for your MD. I misplaced my instructions so contacted support for help with a desk top app and they were very helpful and quick to answer so I can attest to good support. I looked at more expensive units and ones that were less bulky but I am happy I settled on this one as no sizing was required and the ring is very comfortable and probably less likely to be misplaced (as I did with my instructions) and being tight on your finger but still comfortable may help to provide accurate readings . I would buy this again, and highly recommend it.

I have sleep apnea and I have been wearing a Wellue O2 Ring for years.. This is my fourth one. Fantastic product. I wear it nightly. It records my oxygen levels, heart rate and movement during the night. When my O2 level drops too low ( I set it at 88% ), it vibrates and wakes me up to improve my breathing. Highly recommended.

The O2Ring has really been a helpful tool to monitor my O2 and pulse. I have worn it daily since the middle of January. Even though I have carful putting the ring on and off seeing how delicate the band was, it broke today. I can’t find a replacement band anywhere. Does anyone know if they are available?

Works really well - has been accurate and matched her O2 reading at the doctors office. Highly recommend.

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.

I've been wearing an Oura ring for years and have found it incredibly valuable when it comes to my sleep. Lately, since around the beginning of 2025, I've been noticing a lot of breathing regularity issues - which went from always being 'good' or 'optimal' to 'Fair' or 'Pay Attention' on my Oura app. My average oxygen saturation levels have still been good - usually around 95%. But not the 97% it used to be.Concerned I might have developed sleep apnea, I bought the Wellue O2 ring and I have found it very useful in some areas, and other areas not so much. Here are some positives and negatives:Positives:* You can disable or enable vibration settings if you'd like. I choose not to do this yet. It means if your oxygen saturation drops below 85, for example, you can set the intensity level of the vibration to wake you up.* Very useful data once it is done downloading, and there have been minimal connectivity issues so far.* App is easy to use.Negatives:* The accuracy of the data is highly questionable, because I have been relying on Oura for quite some time and I am a little concerned this device has my resting heart rate about 5 bpm higher than Oura on some nights, and about 2-3 on other nights. Which device is more accurate? I have always trusted Oura, so I decided to wear my Fitbit to sleep and got a month of their premium to make sure I can see all the data. And that matches Oura. So the outlier so far is Wellue.* When my oxygen level drops below 90, which does happen about 2-5 times per night for about 30 seconds to a minute, there is no correlation with my heart beat rising or falling, so I am not sure how to interpret this. I would think if your oxygen drops, you would see either a spike or a decrease in your heart rate and I am not seeing that.* Not nearly as comfortable to wear at night as an Oura ring.* The Premium they offer is useless. I did the 7 day free trial. Don't trust the sleep stages of the Wellue. It is all over the place. Like, I wish I got nearly five hours of deep sleep per night. However, even without premium, you get access to rich data.However, and the reason for 3 stars, how accurate is that data I am relying on? I'd feel much better if the data aligned with my other wearables but they don't very often so I am still wondering what to trust? Should I trust Oura and Fitbit, or trust this, the outlier? I am wearing it as recommended on my thumb as they recommend and the fit seems fine. I have found if I use on my index finger I get a little pain in where the red light is on for some reason.

I love my O2 ring. I have issues with low oxygen when I fall asleep and the O2 Ring alarm on the iphone app and ring vibrations wake me up when my O2 dives dangerously low. They also have WONDERFUL customer service! Almost a year from my purchase I had an issue with my ring. After demonstrating the issue and providing proof of purchase they replaced the ring with a new one. It was totally unexpected that a company still has integrity these days. They even followed up to make sure I was happy with the new ring. Bravo on the product and customer service!
