EMAY Sleep Oxygen Monitor with Built-in Recording Capability | Track Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data

What other reviewers said is true - it fits tight, and is definitely annoying when you go to bed.I felt like my pinkie was in a clamshell and the clam didn't want to let go. Very uncomfortable. BUT, read on...About the Retrofit:Looking for a solution, I rolled up two very small bandaids into little "bandaid cigars" and inserted one on each side of my inserted finger (alongside my finger) which provided a slight (very slight) "opening" of the clamshell to support my finger. When I did this, it worked well for comfort, I did not feel like my finger was squeezed an a clamshell all night long, and the device still recorded my data even with the retrofit keeping it just a tiny bit less tight. The key here is to insert a little extra padding on the white edge where the "clam" closes -- vs. a lot of bulk -- just a hint of extra padding so your finger isn't squeezed so tightly. If you opt to ry this, just make sure it's still recording data (look for the blinking light). If it's not, you've payed it open too far and it's not picking up a reading.About Keeping it on all night:It fell off once during each of the 2 nights I used it (I reconnected it when I woke during the night - then it continued recording data). So far I have not used the velcro strap designed to help keep it on - haven't found that necessary - I don't move that much during sleep.Finger choice: My physician friends told me any finger works for reading your data, so the choice is yours. I put it on my left pinkie since I'm right-handed and it's convenient to have a hand free during the night.Connecting & Reporting to the App:Setting up the app was super easy.Not entirely sure how to make sense of the report it spits out into the App, but the data looks clean and the graphics are pretty simple, so I'm sure I'll figure that out.Batteries:It's an energy eater - you need to replace the batteries (2 AAA) every 3 nights or so.I use rechargeable, so it's no biggie.Rechargeable batteries and chargers have come down a lot in price the past decade or so, so it's the way to go.Rechargeable batteries require special recycling, so don't throw them in the regular trash give them to your local recycling center.So far, happy with the purchase. It's nice to have a pulse ox that records data.

I've been using the EMAY Bluetooth Pulse Oximeter for a few weeks now, and I’m genuinely impressed with how well it performs. First and foremost, the accuracy is spot on. I’ve compared it with readings from professional medical equipment, and the results have been consistently reliable and trustworthy.What really sets this device apart is how comfortable it is to wear overnight. The soft sensor design fits snugly without being intrusive or irritating. I often forget I’m even wearing it, which is a huge plus for anyone who needs continuous oxygen monitoring while sleeping.The Bluetooth connectivity is another great feature—syncing with the app is seamless, and the data is presented clearly and is easy to track over time. This has given me better insights into my nighttime oxygen levels and helped me spot trends I wouldn’t have noticed otherwise.If you’re looking for a pulse oximeter that combines accuracy, comfort, and smart features, I highly recommend giving the EMAY Bluetooth model a try. It's definitely a worthwhile investment for peace of mind and better health tracking.

The EMO-80 is an incredibly well-designed, accurate (I compared it to several other oximeters including my doctor's and my Apple watch), and useful product. The graphic displays and summary reports are easily accessible in the app, and they present, in a very user-friendly and professional way, all the information that is needed to assess reduced blood oxygen levels, to identify sleep apnea and its severity, and to check the effectiveness of sleep apnea remediation devices. The battery life is quite good. Using alkaline batteries, I get 6 nights of all night recording which is a couple of nights more than I expected with all night use. A minor positive point is that the device comes with, not one but two, sets of batteries and they are alkaline batteries. I don't know if you've noticed, but anything I have ever bought that comes with batteries always come with shorter-lasting non-alkaline batteries.
