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

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 will absolutely recommend this product! This has helped me have a greater piece of mind and has really impacted how I sleep and live my life. I also suggest listening to my review to find out why!

This is a useful item that appears to generate reliable (or at least sensible) oxygen data while you sleep. I found it comfortable enough to sleep in even though I have very small hands, and though the app wasn’t incredibly intuitive at first, I did figure it out. Downside, at least with my use, is that it needs to be charged pretty much every day, and if you don’t remember to do that, it quits overnight without capturing O2 in the wee hours if the morning, which for me is the vulnerable spot.

I bought this to monitor my O2 overnight because I have breathing issues. I like the product and the information it has provided has been VERY helpful to me and my peace of mind. The product seems well built and has worked perfectly. The documentation does not explain the readings very well, but I found a bunch of information online that explained in detail all of the parts of this piece of equipment and what the information means. However, there are some tricks to getting the most reliable readings. Finger position. Before you use this over night, take a few minutes to test the finger position of the device. Put it on a finger and turn on the App, and go to the Dashboard. This will show you O2 and heart rate, PLUS the strength of the O2 pulse signal (green bar graph on the right). I found that putting the device on different fingers, and on different parts of each finger, made a HUGE difference in consistent readings. The device, which uses a rubber band type attachment around the finger, can be uncomfortable on larger fingers and for extended periods of time. The device works best on the meaty part of the finger and I got the best signal on my left index finger. So, play with it. Put it on, give it a minute to catch up, and see which finger gets you the most green on the graph. YOU MUST HAVE A FIRM FIT AND GOOD PI TO GET CONSISTENT RELIABLE READINGS. This is important because if the device is too loose on your finger, your graph in the morning will be all over the place. Too loose and it slips around and does not get enough signal. Move off the meaty part of the finger, for comfort, and you get poor signal. This can give you extremely unreliable information. Once I found my right spot, and left it there, and got used to the device over night, my results were consistent and reliable. This has helped me find the best sleeping position to get the best O2 overnight. It has also alleviate my fears of sleep apnea. Its been well worth the purchase and I recommend the product!

My first one worked well for years. It started rebooting in the middle of the night, waking me up multiple times. I thought it may be the age of the unit. I purchased another one in April. A month later it's doing the same exact thing. I reached out to customer service and they wanted me to get out of bed in the middle of the night and video it coming back on in order for them to help me. Just purely stupid. I've recommended this product to many people. Now I'm sorry I did. Won't happen again!

I purchased this item because it was cheaper than a sleep study which my insurance (if it covers it) would cost about $700. I became concerned about OSA when my smartwatch measured my SpO2 sometimes as low as 79% when I slept and my wife mentioned that my snoring has gotten worse in the last few years. This device only shows be dipping a smidge below 90% for a few seconds and I am inclined to believe it because this item was designed to measure SpO2 continuously and my watch only has SpO2 monitoring as a feature. I want to be clear that this item is in no way shape or form a substitute for a sleep study and if you have concerns that you may have OSA please talk to your doctor about that; but for an otherwise healthy person, this item can offer peace of mind. Great product! Intuitive to use (app driven, asks for your age, weight, height and sex assigned at birth), and minimalist design does not disrupt sleep. 5/5 review from me!

CONTEXT: FYI - My purpose for the O2Ring is to be a convenient oxygen ALERT device (so I could safely reduce POC use to only when needed), and thus this review does not address data/history/app aspects. REVIEWs: (difficult to give an overall rating at this point, but 3𖤐 for now?) Purchase 05/14/2024 5𖤐 FLAWLESS! for 1 month and 1 day, until issues* Replaced 07/30/2024 4𖤐 GOOD for a few days, until issues* Replaced 10/23/2024 5𖤐 FLAWLESS! so far... :) will update review/rating Monitoring - FLAWLESS monitor & vibration Alert! Ease of use - EASY! Upload app (initially), charge, put on, auto-connect, and bingo. Comfort - YES & I can actually use my hands, but obviously bigger than a typical ring Information quality - Unknown, I haven't yet paid any attention to the app history info Functionality - YES Accuracy - YES +/-2 of clunkier, pincher-type finger device Battery life - GOOD, at least 8+ hrs, though I haven't tried longer (I just turn O2 on in eve when sit/eat) Value for money - YES definitely for my needs. Even w/issues, if THIS one will keep working. Customer Service - GOOD after a slow few weeks to get their initial response. And EXCELLENT at replacing once tech assistance couldn't resolve issues via email. And Issues: The ring just stops waking up anymore even after countless charges, tries, adjustments/settings (finger placement, bluetooth, phone app), lens cleaning, and other tips from customer service and internet. I'm hopeful to favorably updating this review/rating w/an ongoing, successful 02 Ring!

A little pricey compared to the simple end-of-finger oximeters, but if your measure of value is accuracy, then this item is worth it. Mechanically simple (just slip it on) while software-sophisticated with its own app, it delivers accurate information right out of the box. No more "try a different finger" approach to getting your actual blood oxygen and pulse information.

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.

A few days into using this product, I'd say that overall I'm very happy. One thing that caught me off guard though is that if you have this on you while walking, you can get sudden low oxygen readings and warnings being triggered. Looking into this some more I found out that one must stay still and keep the hand still while taking a measurement. Just something to be aware of so you don't go into a mini panic attack like I did 😅 The Apple Watch that I have will detect movement and warn me to keep my hands still. Once I started doing this then I saw the blood oxygen levels going back to normal again.

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.
