WellueO2Ring Oxygen Monitor with Vibration Reminder -Bluetooth O2 Pulse Oximeter Rechargeable, Continuous Recording of SpO2 & PR, Blood Oxygen Saturation Tracker with Free APP & PC Reports

I'm an experienced user of the Wellue wristband-ring system and have been generally quite happy with its performance, but I'm pretty impressed by some of the design changes in Wellue's "02 Insight Ring." First, ease of use: the old system required attaching both the hard drive wristband (to your wrist) and then inserting the ring's chord into the wristband hard drive. The O2 Ring reduces that slightly cumbersome procedure to one step – simply slip on the ring! In other words, they've collapsed the ring and wristband into one device.This design change has more than a simplifying effect, I suspect. Perhaps more importantly, it reduces by half the wear at the critical hard drive connection. Anything that reduces the number of times you need to insert a USB-type connection is a good thing. Eventually, as anyone who works with computers knows, those kinds of connections are generally the first problem you encounter as the connection tends to grow weaker with use and usually at some point simply dies. The only connection you make now is from the O2 Ring to a charging device or your computer. I just hook it up to my computer and leave it attached to recharge from my computer, reducing the connection process further.Another design improvement is the display sensor. In the wristband-ring design, the wristband display of oxygen levels and pulse rate is motion-triggered: that is, a shake of your wrist will cause the display to light up. Not a bad thing, but that means the display is being constantly triggered as you move around at night. I'm not sure this causes wear and tear on the unit, but it surely shortens the battery life. The 02 Ring, however, isn't motion-sensitive: you need to "swipe" the ring surface to summon the display. Kind of like how you open an old Kindle. So you only see the display when you choose to.Yet another improvement I noticed was in the ring band itself. In the original wristband-ring configuration the elastic rubber ring has a tendency to wear and break at some point. In the 02 Ring model, the elastic rubber ring has been reinforced! Excellent preventative measure, in my opinion.Otherwise, the function remains the same. Just plug the O2 Ring into your computer or use a phone app (I use my computer) to get a reading on your night's sleep. It is totally compatible with the simple and nice function of the software. My computer already had the software from the wristband-ring model, and it worked perfectly with the new 02 Ring. I don't actually remember installing the software – other than that it was easy to do. The Ring's brightness, display, and other features can be adjusted to your taste (see manual). I have yet to read the manual; the Ring is so intuitive that I was able to easily use it right out of the box!Though I'm not a "medical professional," I've devoted considerable time into investigating methods of improving my health, and what's more basic to health than sleep? If you snore or wake up feeling headaches or fatigue, you owe it to yourself to monitor what your body does while you sleep. The Wellue system gives you a clear picture of your heart rate, blood oxygen levels, and motion throughout the night. It takes the guesswork out of how you slept. Large plunges in oxygen levels, for example, can spell major problems – and could lead, according to current medical lectures, to stroke and heart disease on top of just not feeling rested and ready to take on your day.I was able to greatly improve my sleep with the Wellue units when combining their information with oxygen therapy at night. For me, Wellue + oxygen concentration machine has made my nights enjoyable again, and I usually wake up feeling refreshed, my brain clear, and ready to take on the day. I wish the same for all of your who suffer from sleep issues.

"The Wellue O2 Ring is easy to use and helps check oxygen and heart rates while you sleep. It vibrates if your oxygen is too low, so you can stay safe. The battery lasts all night, and the app lets you see and share reports with your doctor. People like it because it’s comfy, works well, and has awesome customer service if there’s a problem. If you have sleep or breathing issues, this ring might be really helpful!" THis can be valuable if you have aging parents are concerned with Oxygen saturation in the blood. Or are suspicious of undiagnosed sleep apnea. Reports are simple to understand and can lead to awareness of potential concerns.Wearing the ring on your finger takes a couple of days to become aware of the extra size to prevent from bumping it accidentally. Charging and data sync from the provided USB is a breeze.

Great product! This does everything I hoped it would. Setup was easy with an app. Then you just wear the ring, it powers up when you put it on and the data gets stored in the ring. It recharges via micro USB. You can view live stats on the ring or in the app. You can also open the app later and the data automatically downloads to give a history of oxygen levels and heartbeat along with a motion. It allowed me to see when oxygen levels go lower and for how long. It has alarms if your oxygen drops below a level that you select. The ring can vibrate a lot, a little or not at all. The app can also sound an alarm if you want that. I’m close to getting an advanced CPAP so I can now see charts for before it’s usage and then during use once I have my machine.

I recently got some suspicions that I may have some sleep apnea going on, or at least some snoring. Wanting to be proactive, I ordered this to wear at night after I received a very similar looking device from a home sleep study company.This unit does seem to be quite accurate, quite easy to use, easily lasts all night on a single charge. The download feature is a little unusual and the app feels a little different design language than what I would consider a "best in class" app funcitonality. It does fully integrate into Apple Health.I would buy it again.

Battery life is decent.Accuracy is off by a couple of points as measured against multiple professional devices while in the hospital. Thin strap that closes the ring, and need to keep the ring on, is just cheap and has already failed.Overall, price is too high for quality of product.UPDATE: Multiple attempts to ask the manufacturer how I might repair the strap myself, never asked for anything other than advise, they refused to answer my question and instead insisted on knowing what my "Order Number" was. Custom service is an outright joke.PRODUCT IS OVERPRICED AND QUALITY IS CHEAP.AVOID THIS COMPANY AND PRODUCTS.UPDATE-After this review the company reached out and offered a refund, "reply with full refund" they said. So, I replied. A week later, no reply, no refund. I replied again. Again a week later no reply, no refund, NOTHING.Seems customer service is as reliable as the products.Lesson learned.

I bought two but one failed to display. Contacted the maker and they replaced it.Works well with the app to save data and add to history. Like the apps’s charts and ability to set the rings parameters.Will work to help you provide insights into oxygen and heart rate levels through a night’s sleep. Your doctor can use this information to decide if you might need further detailed sleep study.
