Title: Amazing Product
Review: This product is AMAZING. As a nurse, I cannot believe how well this pulse oximeter works and that the price is so very reasonable. It is simple to operate. The product paired with the app seamlessly once downloaded and it is extremely functional. I love that you can create profiles for multiple users. I highly recommend this product. I was concerned the pulse oximeter would fall off while sleeping, so we are using the little rubber strap to secure it to the finger when in use. It has kept the puls ox securely in place all night.

Title: Should it be looser-fitting for bedtime? Yes, but with a little retro-fitting, it works fine…
Review: 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.

Title: Worth every dollar!!
Review: The EMAY sleep oxygen monitor is a win!!!It was perfect right out of the box and the price is , honestly too low for how well it works. The readings have been consistent and with the finger strap it stays on all night and reads perfect. And I am all over the place when I sleep!! The reviews about the battery dying fast , I believe are people who forget to shut it off. The manual says 3-5 nights in the first couple pages but my battery (supplied two sets by the way) are still going.The app works great and connects everytime . Shows great info as well. Who would want to keep the all that info on the small device. Download and use for doctor or your own info!! I use this with my cpap machine at night and it has shown me my progress and if I am consistent. Great job EMAY!!

Title: Even with one short coming, I am very impressed.
Review: Update 5/1/20:Adjusting my rating to 4 stars after more use.This device has been incredibly helpful in tracking improvements or declines in O2 sats through the night. My research into Covid 19 has revealed possible mechanisms for the oxygen starvation that occurs in Covid 19.This O2 starvation seems to mimic that found with high altitude sickness. This led me to focus on certain supplements, one of which I was already using and have a good deal of experience with as a NAD+ repleter.As a result of my findings, I decided to add a new supplement. This one was created to help increase O2 sats in higher altitudes (wish I had known there was such a thing on a recent trip to Santa Fe).I was already running in the low 90’s during the day, sometimes dipping into the 80’s, and didn’t have a real clue what was happening at night. I used this device to establish a good night time baseline, then added the new supplement – AltitudeRX. I have been able to track a steady increase in my O2 sats at night with this monitor, both in the gradually inceasing amount of time staying over the SpO2 threshold and in the detail the actual graphing provides.I am very impressed with this device, the app and the data it gives me. I highly recommend it.The only reason this is not receiving a 5 star rating is because of a short coming in the design of this device. Unlike a regular pulse oximeter, this one only functions if memory is available. This pulse oximeter has a 40 hour memory, and once it is full, you can no longer use it in any capacity until you empty the memory.However, to empty the memory, you must use the app. If you don’t have a device with the app available, and you run out of memory, this little guy doesn’t do anything. It doesn’t even continue letting you see real time readings even though it can’t record.I can’t see a good reason for crippling its most basic functionality like that. It seems to me it should be a very simple thing to allow it to continue displaying measurements even though they can’t be recorded. There also could be built into this the ability to overwrite the oldest data if someone is unable to download in time.IMHO a device like this should always be able to operate as a simple, basic pulse oximeter regardless of memory constraints. This should be a pulse oximeter first and always, and a recording device second.Original review:I have only used this for a few days/nights and would normally give this more time before writing a review, but I have to say, as a retired RN with critical care background, I am thoroughly impressed.This device is easy to use, has a nice, easy to read display, and is generally comfortable to wear. Besides the first pairing taking a few attempts, the only issues I have run into so far have been: 1) the first night when I used it on my index finger, my finger rolled enough to where it could no longer pick up a reading after a couple hours, and 2) when I tried it on my thumb, after an hour it was putting my thumb to sleep. I then tried it on my middle finger and had no issues. It recorded my pulse and SpO2 throughout the night without any difficulty.The app is intuitive, streamlined, east to use and quickly connects to my oximeter and downloads the data. The graph is easy to access and read; and creating a pdf of a report complete with graph and stats is simply done with a click of an icon at the top of the report.I have used other medical devices for BP and EKG monitoring which connect their respective devices to my phone, and I have to say this has been, by far, the easiest to use.

Review: This is a quality product; it is well-made and its functionality is impressive. The Android app which you can install via the Play Store works fine on my Samsung Galaxy Note 20 Ultra 5G and has a well-designed, easy-to-use user interface. The device clamps on a finger like the ones nurses use in hospitals and clinics. It samples SpO2 (blood oxygen level) and pulse rate each second and can store these measurements overnight while you sleep. I simply left the device on my index finger overnight in bed. A roll of black bandage is supplied but I ended up taking it off as the device stayed on my finger all night without it. The red LED light that shines through the finger did not trouble me as it is not bright, and the display itself turns off after 90 seconds anyway. The end knuckle of my index finger was a little sore the next morning where the device had been clamped on my finger, but nothing serious.Although the device has data storage capability, it can be used as a normal pulse oximeter for spot checks as well. To look at it has the appearance of a standard pulse oximeter, albeit the quality of manufacture and materials is noticeably better than a cheap standard pulse oximeter I already have.The device uses two AAA batteries. Four batteries are supplied in the box, as well as a lanyard, a little storage bag for the device, and a user manual. The user manual explains well how to use the device, and there is an e-mail address to contact the manufacturer if you have any questions or problems. I e-mailed the manufacturer with a query and they replied quickly and were helpful.The user manual estimates that a pair of AAA batteries should last for at least three 8-hour measurement periods.It is possible to view, save and e-mail a detailed PDF report showing statistics and graphs of the blood oxygen levels and pulse rates over the measurement period you have had the device on a finger. The report is impressive and looks very professional, and I would not have a problem showing it to a doctor. In my case I was worried that my blood oxygen level was dropping too low while I slept, but the report put my mind to rest. It is also possible to save or share a CSV (comma-separated values) file which you can import into a spreadsheet if you want to examine or analyse the data yourself.The only things that I found that could be improved are: a) sometimes deleting the data stored on the device took a few attempts; b) the user manuals that can be viewed in the app could do with being zoom-able, as the text displayed on a smartphone is tiny (a printed user manual is supplied as well in any case); c) I could not find a way of deleting a user. I do not consider these significant problems, though.Overall I am very impressed with this device.
