Review: Accurate, reliable and reassuring - I was initially very skeptical about this device. However, after my wife experienced a very frightening issue one night with her oxygen machine, I decided to give it a try — and I’m very glad I did. My wife now wears this ring every night to ensure she is always receiving the oxygen she needs. If her oxygen level drops below the threshold I set, the device vibrates and immediately sends a loud alert to my iPhone. That feature alone provides tremendous peace of mind. She has worn this device during hospital stays and doctor visits. Of course, the hospitals use their own professional monitoring equipment, but every time I compared the readings, this device was remarkably accurate and matched the hospital equipment almost exactly. The included app is easy to use and works very well. It alerts you if you move too far away from the device, and the connection remains solid throughout our fairly large house. The app also stores historical readings, which can be downloaded and shared with doctors when needed. Battery life has also been excellent. We typically get around 16–20 hours per charge. We simply charge it for a couple of hours each day, and it’s ready to go again. Many healthcare professionals who have seen this device have been highly impressed with it. Surprisingly, most had never heard of it before. After about six months of near-constant use, we did experience a small mechanical issue where the device occasionally slipped off my wife’s finger. I contacted customer service, and within a week they had sent a brand-new replacement device — no arguments, no blame, and no hassle. They were friendly, responsive, and extremely easy to work with. If you’re hesitant or skeptical about buying this device, don’t be. For anyone who needs to monitor oxygen levels — either for themselves or for someone they love — this is one of the best and most reassuring little devices you can own. The product itself is excellent, and the customer service fully backed it up.
Review: Excellent product, great service response! - This is an excellent product that does the job flawlessly. It reads and records my oxygen levels, heartrate, and movement in one-second intervals, unlike other wearables that record less frequently or require another device to record the data. I put it on and it starts recording automatically. Downloading the data to the app over bluetooth is automatic, once the app is open and recording stops. The battery life is good, usually enough for at least two sleep sessions. There are only three issues that I have: > The cord that comes with this device is NOT a standard USB-C cord. The device will not charge or transfer data with a standard cord. I have to use the one that came with the device. > The app uses private storage on my phone to write files, which I then have to transfer to my PC, one at a time, using the share function in the app to store the file on my phone, then my phone to my laptop. (There is a way to sync with my PC directly, but this is only from the wearable to my PC using that cable and Wellue's proprietary software.) > This last one is really nitpicky, but there is no way to see the battery level in-app or on the device, except by a very small battery icon. No battery percentage is shown, so it is difficult to know whether there is enough charge for another sleep session. PS: The customer service department deserves a bit of praise for handling an issue I had with my unit where it stopped responding to the button on the device. All they required was proof of purchase and a video showing the problem, along with a photo of the serial number on the device and they shipped me a new one in two days! Amazing!

### ⭐⭐⭐⭐ Worth it if you need detailed oxygen data
*by P***S on September 24, 2025*

I bought the O2RingS to track overnight oxygen and heart rate levels, and overall it delivers very well on its promises. What works well: - Accurate tracking: The O2RingS samples 200 times per second and stores one data point per second, which is much more frequent than the original O2Ring that stores one data point per 4 seconds. This makes it highly precise for overnight monitoring of oxygen saturation, heart rate. It also tracks movement, but it didn't indicate a lot of movement even when I had to get out of bed during the night. - Simple operation: Just slip it on and it starts recording automatically. Syncing with the ViHealth app is quick and reliable over Bluetooth. Data can also be synced to a PC using the included USB cable and the dedicated PC application. There is no difference in functionality between the mobile and PC apps. - Vibration alerts: If oxygen levels drop below a threshold, the vibration is noticeable but not overly disruptive—useful for sleep apnea monitoring. Things to improve: -Charging cable: Although the device uses a USB-C port, it does not support standard USB-C chargers or cables. You must use the included proprietary cable. Losing it could be problematic. - Comfort & design: The “one-size-fits-all” approach isn’t ideal—on smaller fingers it feels loose, on larger ones tight. Bottom line: If your priority is accurate, high-resolution tracking of oxygen and heart rate, the O2RingS is excellent. The automatic recording and reliable app integration make it easy to use nightly. However, the comfort/design quirks and reliance on a proprietary charging cable are definite downsides. For me, it’s a solid 4-star device—worth it if you need detailed oxygen data, but not perfect out of the box.
