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.

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.

Product appears to be good although Wellue Service were slow to respond to my situation. Amazon service is very good.

This device may work well for some depending on what you want to use it for. It did not work out for me. Here are some pros and cons to help you make your decision: Pros: 1. Seems accurate (as compared to another pulse-oximeter I have) as long as you hold relatively still. 2. Data logging is very powerful and relatively easy to use. I wanted a pulse-oximeter for doing sleep studies and understanding how O2 levels fluctuate doing daily activities. 3. Appears well constructed. 4. Outwardly a nice design and easy to use. 5. The PC desktop app is good and easy to use. 6. Despite negative reviews for the phone app, it does have some good features, if you create an account. Cons: 1. The big one. There appears to be only one size and it is too small, at least for me. Strangles finger if worn very long even when worn on pinky (I have average sized hands for an adult male). 2. Also important (to me). If you use it in motion, like on a walk or just mild activity around the house, it will read wrong frequently including setting off the alarm at below 88% O2. The data logger tracks SPO2%, Pulse Rate and "Motion". So it is clear that motion is an important parameter. I think I read somewhere about how these are not good for measuring during exercise so this may be something that pulse-oximeters don't do well in general. 3. To get the good stuff out of the phone app (history/logged data), you must sign-up with an account. 4. The data takes a long time to refresh in the phone app via Bluetooth. So if you want instant gratification, plug in to the PC and use that app. 5. During overnight sleep study, the data logger sometimes randomly starts a new file (two csv files). Then I had to manually merge them in Excel to get a full graph. Not a huge deal but annoying. Things to know: 1. There are two ways to get data out of the unit. One is via the phone app and Bluetooth. You share the csv file with yourself via email in the app. You must sign up for an account for this to work. As noted, the data can take a while to update on the phone. The other is a USB cable connection to your computer and the O2 Insight Pro app on your PC. There is an Export to CSV button. 2. When it is plugged into the PC it displays charging. When the desktop app is run, the unit displays two opposite facing arrows as a symbol of connection. When you close the app, the connection symbol stays so I was not sure if it was still charging. After some experimentation I determined that it was charging. 3. The data file always has large numbers at end from the time you remove your finger to when it stops logging. These are numbers that are out of range for the sensor. If you are going to plot the data in Excel, you need to remove these numbers. This could have been listed in the cons as seems they could write code around it. Not a huge deal. 4. It logs data 4 times per second. This may be a pro to some and con to others. But since the response time of these devices is no that fast it just causes larger data files to work with than needed. Not a big deal. 5. If you use the USB connection to your PC, then export the CSV you get a nice file name format that contains the year, month and day like a digital photo does. If you transfer the data to your phone via Bluetooth and email it to yourself, you get a random series of numbers in the file name. Also, the data format of the two files is completely different. The PC file includes an AM/PM type time stamp and two additional data columns. The phone app uses military time and the Day/Month/Year format found more in Europe.

Performs well, easy to use, has both phone app and PC app. The data can be loaded into OSCAR (Open Source CPAP Analysis Reporter). For me, it is less noticeable than the rubber cup finger sensors with a separate wrist component. I started with one of those because it was cheaper, and if you only need it for a short time or very occasional use, that style might be fine. But, I use it every night. It does seem to be a bit on the small side. My hands are men's med/lg, I'd say. I usually wear it on my ring finger, sometimes pinky. But, the band is rubber, so I can get it on my other fingers. My concern would be if you are a big guy with large hands you may be limited to your pinkies. I've been very satisfied with my purchase and would buy it again.

I’ve been using this ring for a while at night and it’s been helpful in letting me know when my O2 is low or pulse is erratic. The ring works with a nice app that provides 24/7 reporting of your results. The app is easy to maneuver through and you can add notes at the bottom of the reporting page. I mainly use this at night, to monitor my O2 levels. .
