Wellue O2Ring-S Oxygen Monitor with Vibration Reminder Bluetooth Pulse Oximeter Tracks SPO2 and Pulse Rate 24 hrs Battery

We love the O2Ring-S Oxygen Monitor. My wife has a lung disease and we can tell ahead of time when she needs to sit down and rest or increase her oxygen on her consentrator. We had an issue with it months later but customer service was awesome and got a replacement in a timely matter after. Actually it was the best customer service I have ever dealt with! This is the 24 hour model but we also have the 16 hour model that we use for a back up while on vacation plus wanted one to monitor during the night occasionally so 16 hour one comes in handy the next day why 24 hour one charges. Later we'll probably buy another 24 hour one to switch off every day. My wife says it is comfortable to wear and never had an issue doing so. Every morning I download the data to my cell phone and then to my computer. That also helps to see monitor what she shouldn't be doing or take more breaks if she does. Needless to say, we are very happy with the product and the company's service department. I wouldn't have a problem buying again because it's a great tool on help keeping my wife safe! Here is a small sample on what we see in my downloads every morning on my cell phone. Read more

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! Read more

In some respects it's a good tool for determining O2 blood saturation and how it tracks all night and gives a full report. It wakes you up with a vibration if 02 level falls below a preset level. The big problem with this device is that it broadcasts very high bluetooth EMF levels all the time while it's on. I found this out using an EMF meter. It's in the red zone of the meter all night long averaging in the range of roughly 105 mW/m² even when the device is not paired with a phone and the ViHealth app is completely closed or uninstalled. My finger is a bit sore and numb where I had it on nights for about a month. This is poor design and a health hazard over time. My wife suffered severe Parkinson's symptoms using bluetooth earphones that slowly went away over about a year after she stopped using them. All my bluetooth hearing aids allow me to turn continuous bluetooth off . Nobody should be exposed to so much continuous radiation. One should be able to shut bluetooth off if desired and then turn it on briefly while communicating with the app, like downloading the nights data. I don't think I can return it now though I'm going to try. It's too bad - an otherwise good tool but somebody in the design of the product apparently thinks high levels of EMF are not a health risk. I know otherwise. They could program it to poll for a signal from the app every 30 seconds or so instead of having bluetooth on continuously whenever the device is turned on. And the signal level is much higher than it needs to be. That's what my hearing aids do. I checked with my EMF meter. Full blast EMF all night long. Read more
