I was recently diagnosed with Atrial Fibrillation (Afib). This works great for tracking my condition while sleeping. I was worried that it wouldn't fit, since it looked big in the product pictures, and I have skinny fingers/thumbs. It fits nice though. Not too big or small, and it's comfortable. I was also worried because some reviews said that it was not accurate, but mine seems to be really accurate. The heart rate matches my Garmin 405CX (w/chest strap) and my Emay portable ECG. The oxygen levels match the small pulse oximeter I have within 1%-2%. 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.

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. Edit: I had a bunch of connection issues and contacted the company via email. They ended up sending me a replacement and it’s working well and aligning with my Oura on heart rate and also providing valuable data into some nights that I have sleep apnea episodes.

Loving the information provided, seems to be accurate with my sleep,study. Easy to wear & the app is simple. Love that I can export the data to excel too.

Works well

This is the 4th new device I have had in the last 3 years. Two were replaced under warranty. The O2 and Pulse readings are quite accurate and the monitoring app is excellent. I am hoping for more reliability now.

Works great for me. Easy to wear and track data.

The device does what it says on the box; monitors your SPO2 levels. Just to explain, I've had open heart surgery (triple CABG) and I use a CPAP machine. 2 reasons to monitor oxygen levels. I was originally looking for a finger-clip style O2 monitor. I've been using the O2 ring for a week now and have had to only contact support once. The device wasn't being recognised by the PC software. The device is both bulky and fragile. You have to take care when removing clothing over it as you could break the elastic sensor ring. It's easy to forget it's on, so be prepared to quite often get it caught in your clothing. The elastic ring has an expansion section. I don't have large hands but I found that it was quite tight even on my index finger. You can wear it on (in order) Thumb, Index, Little finger. Not middle or ring fingers. I found wearing on my non-dominant index finger worked best. On the little finger it was too loose and kept coming off overnight. The instructions warn against squashing the sensor in either direction; flat against the display or from the sides. This makes it very difficult to hold when attaching the charging cable or removing or attaching the ring to your finger. I found that holding the device at either end of the display to be safest. Unfortunately this puts a bit of strain on the elastic sensor ring when attaching or removing the ring. The device connects to your PC via a "special" read proprietary and expensive cable ($40 USD at time of writing, so don't lose it or break it). When connected to your PC you can use the Wellue O2 ring software to download your 'session' data. But there's a trick/trap. You have to make sure Bluetooth is OFF on your phone (so support advise, however I suspect you can just move your phone out of range or turn it off. There's NOTHING you can do at the ring itself to disconnect Bluetooth) You can then connect the cable, start up the software then wait for the ring to connect and download the data. Once you've downloaded the data you can then disconnect the cable (and cease charging the ring), turn Bluetooth on your phone [ I've found the Bluetooth connectivity to the phone to be a bit random. Sometimes it works, often it doesn't. ] Note that the cable is also a charging cable. I haven't yet checked whether I can charge the device using a 'standard' charging cable while also having it connected to the phone app via Bluetooth. I'm not sure how this might help over say a finger-type O2 monitor for around $30 (less than the cost of the data/charging cable for the O2 Ring), other than the logging facility. For the money spent I can't recommend this device UNLESS you suspect you have serious O2 issues that your health professionals do not accept. This will allow you to prove to them that you have O2 issues. [ In my Country we don't get a subsidy for devices like this so it's cheaper to just make dozens of visits to the doctors and specialists. ] In summary; at the price I can live without it. If it broke outside the warranty period I likely wouldn't replace it. Perhaps I might change my mind as firmware development improves. Hope this helps. Stay safe.
