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

very useful and comfortable to wear
I’ve used this ring oximeter for years. Generally I wear it at night. It gives a very accurate measurement of O2 throughout out the night, as well as a useful summary of how much time was spent in various O2 ranges and how many times O2 drops. It also has various alarm settings which i disable. The last thing i want is to be woken at night when my O2 drops, but it may be useful to some people. One thing i like a lot is that it gives the time when you tap it. I wake up frequently at night an like to know what time it is without looking at a clock that sheds light all night long. The app on the phone is easy to use. I lost my original ring on a recent trip and just bought another, which is why I write this review now

Great. Exactly as advertised Simple to use.
These O2 rings are accurate. They keep a continuous record of oxygenation, heart rate, and movement all night (or all day). The battery has lasted me over 12 hours. It probably lasts longer than that but I haven’t worn it longer than 12 hrs.The app gives you the ability to view and print a full page, detailed report covering the entire night. The report is in color, so it is very easy to read. I recommended it to my 82 yr old brother, and his report indicated low SpO2 at night. His Dr ordered a sleep study (pending) based on the report.

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.

The ring works well and does what it says it should. Compared to an in-hospital pulse oximeter, the results on the ring match the results on the hospital equipment. For the money, would be nice if the hardware had a better build quality. I’m not sure if it will last more than a year, but perhaps with care it will? The PC software is finnicky, you need to connect the cable, start the software, then connect the ring in order to do a download. Once you know the order, it works reliably.Overall, happy with the purchase. A better build quality would see 5/5, particularly given this isn’t a cheap product.

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.
