Recently I was feeling fairly exhausted in the day time and having a feeling that I wasn't sleeping soundly. I don't know if it's because I haven't used my CPAP machine for 2 years. But I don't have a link to my CPAP records anymore so I figured I'd get this cool, lightweight little ring and use it to do my OWN sleep study. Well, of course, I had 02 levels in the low 80s about every 2 hours all night! So i got out my CPAP and wore it at the first night. The results were kind of surprising. It seemed that I had some problems but I slept through the entire night with my CPAP. Now, I won't use my CPAP without this little ring. It is comfortable, is most likely accurate, and it is really an incentive to use my CPAP machine because after adapting to it, my oxygen level never in the 80s now. If you like to have instant feedback for using your CPAP machine, this little ring did that for me. The phone app works well. You can download your results to a pdf and show it to your doctor if you want a professional sleep test in center.
This is a very user friendly SP02 device. If you have breathing issues like I do with my sleep apnea, this ring should work for you. I believe the SP02 results are more like to be the most accurate. I like that it connects to your phone quick and easy. I like that it keeps track of your levels continuously and you can even print out the information and give it to your doctor if needed. This will also alert you if your levels drop out of range.
Nice product! Wearing it doesn’t bother you much during daily life. Data works with your iPhone so works pretty well. My doctors were very impressed with its accuracy as well. I would recommend.
I purchased it because I am having exertional oxygen desaturation. I was concerned that it would be too bulky and disrupt my sleep but it is pretty comfortable. I'm satisfied with its easy operation and accuracy. Its readings are accurate based on my other devices. I cannot imagine what else you could want out of this device. I would recommend it for anyone trying to track their O2 stats.
Reliable and accurate! I got one and love to take it out when travel. You can wear it at night so it vibrates to remind me to sleep on me side. I on the other hand got a CPAP and it helps me monitor with the data it produces. You just need to go to bed, put the mask on and wear the ring to monitoring your oxygen saturation over night time, and check the record in the morning. I keep adjusting and am moving from the low 5 rating into the upper 8's for O2 score.
This device is much beyond my expectation! The results are reliable, and it's very easy to use. I put it on my finger right out of the package and it was already giving me a Sp-O2 and HR reading. The app was straightforward and easy to setup. I've ordered another one for my father, who just left the hospital after having COVID, pneumonia, and kidney failure. He’s in rough shape and now on oxygen at home thanks to the virus. He’s been using this tracker to keep an eye on his Sp-O2 levels in particular. He said that when he is off of his oxygen tank, his Sp-O2 reading goes down into the 80s, but on oxygen he maintains 99%. He tested this tracker against his another Sp-O2 reader and this Wellue device does a much better job. It is consistent, accurate, and reliable. He has been using the tracking app every time he gives his doctor an update. This device has been way more helpful than I could have ever imagined. I’m so thankful that a product like this is available on the market for regular consumers. This little device brings so much peace of mind to our family.
I decided to buy this device because I have been tracking my wife’s oxygen levels while she sleeps at night using the regular finger reader device and it’s exhausted for me waking up by night, taking the finger reader, see the reading and write it down in my phone. I have found this device very convenient and allowed me to sleep more while she is being monitored by the device itself. Just a small inconvenience, its battery doesn’t last long. I have to charge it every day. I like the ring so far.
Delivery was fast and trouble free.
Product itself is working accurate and flawless so far (Pulse Oxymeter ring)... the only negative is that I feel it is a bit pricey compared eg to a smart watch providing the same and more functions.
