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

Amazing to help with my overall health!
I recently started using the Wellue O2 Ring, and I can honestly say it has transformed my sleep experience! This remarkable device seamlessly syncs with my CPAP machine, making monitoring my oxygen levels during the night easier than ever. The low-level alert feature is a game changer; it gently wakes me up when necessary, ensuring I stay safe and comfortable throughout the night. I can finally rest easy knowing that my well-being is being actively monitored while I sleep!What I love most about the Wellue O2 Ring is how incredibly user-friendly it is. It fits snugly and doesn’t interfere with my sleep at all, allowing me to drift off without any distractions. The combination of its effectiveness and comfort has truly exceeded my expectations, and I wholeheartedly recommend this product to anyone in need of reliable oxygen monitoring. If you’re looking for a solution that prioritizes your health and enhances your sleep, look no further than the Wellue O2 Ring!

Take this over a CPAP any day!
I did a sleep study and found that I would stop breathing 25 times an hour on average. Doctor said I needed a CPAP. I knew about the CPAP machines and had traveled with friends that had used them in hotel rooms and know 100% I’d never be able to sleep with that machine, so did some online research and found the Wellue O2 ring.The results are beyond positive, it is simple and it works! My sleep quality has improved greatly. In the beginning, it would catch me dropping in O2 levels quite a bit, but as time went on, it actually trained my body to where I don’t even need to use it every night. It took a few months to get here, but I feel much more rested these days.

The device just works, is semi comfortable to wear all night and gives good insights into your ox, movement and heart rate. Great at doing what it was designed for.

Got this for my mother (who has a lung condition) and overall we have been quite impressed, we use this as an alarm as to when she needs rest and focus on breathing during the day. so for anyone not using it for sleep tracking it works well for use during the day. A few improvements we would like to see would be:1. better battery life as the battery life lasts 8-10 hours in real life2. better app, while the app serves us well for basic information it could be made better with interconnectivity for other people to view (pay wall doesn’t even work when we try to set up remote view).3. there is a 2-3 minute delay (letting the algorithms do its thing i’m guessing?), it appears from when you start to move or breath poorly and when you get the alert on your ring (vibration), we have compared it to other oxygen sensors (over the counter and medical grade) and while it is accurate the tracking time is delayed. Would be nice if the data loop was shorter and was a little closer to real time data (<20 seconds).

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.
