- Wellue O2ring Pulse Oximeter - Rechargeable Bluetooth Oxygen Saturation Monitor with Reminder| Wearable O2 Meter Continuous Tracking of Oxygen Level and Pulse Rate with Free APP & PC Software

I was SO IMPRESSED by this perfect little pulse oximeter that I felt compelled to share my opinion of it. I was hesitant to purchase any device, especially something for my wife, because I've been so unimpressed by convoluted user interfaces and difficult-to-use IoT gadgets in the past. But this little device is a true joy to use. The device itself has just one touch-button which simply lights up the screen to show its current readings. Its illumination can be set (by its apps) to low, normal or bright, and I recommend bright if you'll be viewing it outside or low if you'll be viewing it at night. Its clock and calendar will be set the first time it's connected to its apps. Again... the little device has no user interface other than an illumination button. That's all it does, since that's all that's needed. There's no on or off or anything else. You slip this onto a finger, it senses that it's being worn, so it turns on. If you take it off quickly, it resets and shuts down. If you keep wearing it, it begins logging once it's sure that you mean it. If, while it's logging, you take it off, it displays a short countdown from 10 to 0, giving you time to move it to a different finger, change your mind, or whatever. If you put it back on, the interval is ignored and logging continues. If you allow the countdown to expire, that session is ended. The device retains data for the most recent previous four (4) sessions. When you record a 5th session the oldest one will be replaced with the newest one. The device should "live" on its power cord. In other words, take it off and plug it in... so that it will always be fully charged whenever it's needed. You should think of it as a single charge per use. The battery is stated as 12-16 hours, so a full night's sleep will take it well down. So just be in the habit of keeping it plugged in. The mobile app for iOS is slick and perfect (and I assume that they did the same for Android). You do not "pair" the device's Bluetooth with your phone. Rather, the mobile app finds it and links to it. A single app can be used to collect the data from multiple devices if you wish. When the linkage occurs, any newly recorded sessions that the app hasn't already downloaded and stored will be obtained. The Windows desktop app works equally well. Using the included USB-A style interconnecting cord (you must use the one they provide for PC data retrieval) your device will be found and, as with the mobile app, any data that has not yet been downloaded, will be. Both mobile and desktop apps can show current and historical data and can dump to CSV (comma-separated value) or PDF report formats. And the use of one does not "take the data away" from the other. Each obtains any available session data that it hasn't already obtained. Having seen how well this works for my wife, I purchased a second device for myself so that we can use them at the same time. In one day she learned some very valuable information about the state of her respiration. Anyway, that's it. Five thumbs up for this little gizmo. It probably deserves your purchase. And if you think that this review was helpful and deserves to be seen by others, please take a moment to click that this was helpful to you. Thanks!

In 2021 my husband was hospitalized with Covid. He was in the ICU for 3 months. During this time he had several lung related issues that resulted in severe scarring of the lungs that affects his oxygen levels. When we brought him home from the hospital I needed a way to see where his oxygen was at through the day and night. A ring that would sound alarms if his oxygen dropped below a healthy level. I spent hours researching all the different rings on the market and decided to give the Wellbu ring a try. When the ring came we put it on one finger and a pulse ox on another finger and they were within a point from each other or the same. As we would do his physical therapy it was crucial to know when his oxygen would drop below a healthy range. So we put the ring on his finger and this alerted us while he was doing his walks or physical therapy that his oxygen had dropped below the level we had set and he would sit down and allow it to come back up again. One of the things we loved about the ring is that it’s one of the few rings that tracks his oxygen continuously from the time he put it on until the time he took it off. Then it saves his oxygen levels in the ViHealth app from every time he wore the ring that we were then able to take to the pulmonologist and use this to help us make important decisions relating to his improvements. The other great thing about the app is when his oxygen dropped we could zoom in and track the time period from when it started to drop and how long it was low for. You can zoom in and get a close up view of exactly where his oxygen dropped to, it puts a triangle on the graph of where the alarm sounded. You can drag a line across the app and it tells you exactly how low his oxygen got to and when the alarms sounded. You are able to choose in the app at what point you want the alarms to go off with the heart rate and oxygen. When the alarm goes off on your phone of which you can also set a sound level for the alarm in the app. But the ring also vibrates when it hits the warning levels you set for it. This was convenient in the night because when his oxygen dropped he would be woken by the vibration and a lot of times his oxygen dropped because it came off in the night so he was able to put it back on without me having to do anything. Of course I knew it was low because of the alarms but a few times I was so tired that I slept through it (because I had it set low, needless to say I turned up the alarm the next night) but he was able to wake up because of the vibration and put the oxygen back on. It also gives you a heart rate reading and motion reading as well this was extremely helpful during the night to know if his oxygen dropped because he got up in the night. From the time I brought my husband home from the hospital my biggest worry was how would I know if his oxygen dropped to dangerous levels again without always having to be watching a pulse ox on his finger. This helped me be able to sleep knowing that if it dropped I’d be alerted. I was able to walk next to him and push his wheelchair next to him as he walked and know exactly when his oxygen got too low and had him sit. We now go for walks around the neighborhood and I open the app on my phone and track his oxygen from there. This is a must have if you have concerns with either you heart rate getting too high or your oxygen getting too low. I would and have recommended this ring to anyone that is looking for a way to track all of this information. It was a game changer for me.

I have used the Wellue O2 Ring Pulse Oximeter for about one year, and use it most nights. It’s been quite comfortable to wear, I’ve tried it on different digits and while comfortable can provide variations depending on your hand position during sleep. I find it has been pretty darn accurate for both O2 levels and heart rate, matching up closely with the HR also tracked by my Whoop. I use their ring to augment data provided by my CPAP machine in order to titrate my treatment pressures to obtain the best results and achieve the best possible therapy. For the accompanying app has been user friendly, there was a point where they wanted you to create a user profile and login but it is not required for use or exporting user data. The ViHealth app provides a good visual and it’s easy to maneuver in the HR or O2 sections to check your readings throughout the time of use. The app also allows exporting data via PDF or a CSV file. The CSV allows for easy importation of data with other apps or services to monitor your health. The CSV file easily integrates with SleepHQ’s service to help refine my CPAP therapy. The Bluetooth connectivity has been quite good, occasionally it takes a minute or two to connect then start pushing out data but it’s been very reliable doing so. There are times where the internal clock does its own thing but once synced it corrects the data logs automatically. The silicone portion of the ring has stretched slightly but continues to remain snug enough for accurate readings and comfort. Overall, I’ve been happy with the product and look forward to continued use.

I have had the Wellue O2 Ring Pulsemeter for 1 year, and use it every night for about 355 days It is accurate when I compare it to other pulse meters. It is comfortable to wear It has good data visibility with the Vitahealth app. You can zoom in to specific time, and you can export to PDF for your records or to share. it always connects easily via bluetooth to the app I will continue to use it, and recommend it if you like to see your sleep stats. I compare my night oxygination with my snore lab full night recording to monitor if I develop sleep Apnea. I can check both to the seccond because the times are synced through the phone clock. You do have to open the Vihealth app to resync the time when you change time zones. After some time, I think the silicone ring stretched slightly, making the ring a little looser on my finger. My oxygenation drops increased over time and then got better when I put on a new O2 ring. It would be nice if the ring "band" could be exchanged as it wears. I would also like to be able to manually turn the ring off. Overall, I am happy with the product.

I rely on this oximeter to monitor my oxygen levels during exercise. I am a COPD patient, and this works perfect during yoga class. The back of unit strap did fail during the warranty period. The company was responsive to my request to replace the unit. After showing proof of purchase and photos of the problem, it was immediately replaced. I was quite pleased with the great customer service.

Terrible Experience with Wellue Wearable Pulse Oximeter - Poor Product and Customer Service I recently purchased the Wellue Wearable Pulse Oximeter, hoping for a reliable and functional device to monitor my oxygen levels. Unfortunately, my experience with this product has been nothing short of a nightmare, thanks to the poor customer service, the malfunctioning device, and the urgent need for a refund. To begin with, the customer service provided by Wellue has been abysmal. I reached out to them multiple times regarding issues with the product, but I was met with unresponsiveness and complete disregard for my concerns. Their lack of communication and failure to address my problems only added to my frustration. As for the product itself, it has been an utter disappointment. Right out of the box, the pulse oximeter failed to function properly. It consistently provided inaccurate readings, making it impossible for me to trust its results. I tried changing batteries, resetting the device, and following the instructions meticulously, but to no avail. The device simply does not work as advertised. Considering the significant price I paid for this pulse oximeter, I expected a reliable and accurate device. Instead, I received a dysfunctional piece of equipment that has caused me nothing but inconvenience and anxiety. Monitoring my oxygen levels is crucial for my health, and this product has failed me completely. I demand an immediate refund for this useless product. Not only has it been a waste of my hard-earned money, but it has also caused unnecessary stress and disappointment. I implore someone from the company to contact me promptly to resolve this matter and initiate the refund process. It is unacceptable for a company to sell a faulty product and then disregard the concerns of their customers. In conclusion, my experience with the Wellue Wearable Pulse Oximeter has been nothing short of a nightmare. The poor customer service, the malfunctioning device, and the urgent need for a refund have left me extremely dissatisfied. I strongly advise potential buyers to steer clear of this product and look for alternatives from more reliable companies.

I really want to like this ring, and at first I did, because it worked flawlessly. But only for a short while. Three months after purchasing, the on-off button on the ring facedoesn't work at all... zero response to touch but it does turn on when I put it on, so I can still use it. Also the touch display has gradually degraded and is malfunctioning about 75% of the time When I touch, it's completely unresponsive, and I have to take the ring off and quickly put it back on to get the display to come on, so I can see what my readings are. Most recently, I've had to do a factory reset because it was hanging and giving completely erratic readings. The reset helped stabilize the readings, but not the touch issues. I'm using it both with the ViHealth App on my phone and PC as well as importing the data into OSCAR, which is a standalone CPAP diagnostic program. I do like the ViHealth apps a lot. This ring is a great concept, it's comfortable to wear, and when it works - it's an amazing tool. I just wish the build was more robust and it didn't have all these issues... at this point its hard to know if the data is trustworthy given all the problems I've had... If it stops working I would look at other options, because reliability is essential, and this is not an inexpensive tool...

I bought this as I was recently diagnosed with severe sleep apnea, and am going through the treatment phases. Trying very hard to stay away from CPAP! On that front, am trying an oral device... and have had several sleep tests to measure pre and post device results. This is a frustrating process, as sleep tests are cumbersome, and insurance only covers occasional tests. In addition, as I have now learned, results on sleep tests can vary significantly depending on the night! For example, I have now learned that my apnea is worse when I sleep on my back. But two sleep tests I did were tough to compare since one night I slept several more hours on my back than another... That's where this device comes in: you use it every night. It is very easy to use, very comfortable, and generates a very easy to understand one page graphical report that shows O2 level and heart rate overnight (by second?). Calculates average O2 and heart rate for night, as well as some other stats: time with O2 level less than 90%, number of O2 drops > 4%, and number of drops per hour. I cannot vouch for the accuracy of this vs. a full-on sleep test device... but from what I can see it looks accurate. As importantly, because I am using it every night, I can compare results from night to night and see if there are things I can do to influence overnight O2 levels. One thing that it shows is that O2 performance can vary significantly from night to night. Another that it shows, in my case, is that alcohol consumption has a big impact on the apnea. Working on the weight loss thing, but too early to tell if that has impact. However, with this device, I will be able to see if it does much more quickly than if I have to wait for another traditional sleep test. So, this thing is very simple to use, very comfortable, and for me, incredibly informative. I print out the one page report and save it, so that I can compare readings over time. The only glitch I had, and this is minor, is that I had to repair (via bluetooth) the device to my iPhone when the Iphone did an iOS update one night. If you dig into the company website, you find that you just have to take some steps to repair, and after you do it works perfectly (with no loss of historical data). For anyone on the apnea spectrum (is that a thing?), I could not recommend this device highly enough...
