## Customer Reviews

### ⭐⭐⭐⭐⭐ Seems to work well with no glitches
*by L***P on January 8, 2022*

This is an interesting device that seems to work well, I assume it's recording data accurately. I suggest scanning the QR code in the instruction booklet to make sure you're installing the correct app on your phone. Follow the instructions carefully step by step to link it to your phone's blue tooth, it took me a few tries until it was successfully linked and ready to use. The data report is easy to understand. Not a replacement for a sleep study but may offer some helpful preliminary info. I'm impressed with this little device.

### ⭐⭐⭐⭐ Works OK but you'll want plenty of vet wrap and alkaline batteries
*by J***E on May 29, 2022*

I purchased this aqua blue Emay device in August 2021 as part of a larger discussion with a cardiologist about sleep apnea contributing to heart disease. A family member who also has heart disease as well as sleep apnea requiring a CPAP suggested looking into my sleep quality, but I'm not yet ready to commit to a professional sleep study. I figured a $40-60 continuous monitor would allow me to investigate if my blood oxygen levels drop/pulse rate shoots up around the same time in the middle of the night. My experience is that this device isn't medical-diagnostic grade but it does a decent job of tracking you and helping "set the stage" for discussions with a doctor about professional diagnosis via sleep study.Where most $20 pulse oximeters are designed to show a measurement on a display for maybe 30 seconds and a point reading, this $40-60 EMO-80 Emay pulse oximeter starts a reading with the display for 90 seconds, then puts the display into a sleep mode where just a yellow dot flashes in the corner and it keeps recording data until the battery runs out or you remove the device from your finger and then hold the power button. With some Amazon Basics AAA alkalines I can count on about 2 nights per set of AAA alkaline batteries. You may get a 3rd night out of the batteries but that may cut short when they enter lower voltages. When batteries run out, the device seems to record the data from earlier but I think the readings look a little more erratic in the minutes leading up to the power-off. I'm currently looking into some AAA lithium batteries to see how they work out for this device.The kit came with one 1" roll of "vet wrap" cohesive bandage in black color. That bandage is great for comfortably keeping the pulse oximeter from slipping off your finger during the night. It doesn't leave a sticky residue like a tape would and it can be unwound and reused several times. I still found myself buying more 1" cohesive bandage rolls as I've used the oximeter.The % oxygen measurements in my meter seem on the low side by about 2-3% compared to what I see at the Doctor's office. I had to adjust my expectations for the readings based on that (the manual claims 2% accuracy). The app's default threshold for oxygen desaturation is similarly set too high by default, but can be lowered in the app.My experience is that the app is a bit clunky. You need to synch the meter with the app via bluetooth to have the meter get time/date info and upload data. The window to manually review data seems to be at a fixed width so you can either review your night with many pages of side-scrolling through 5 or 12 minute segments or generate a summary report that does a better quick overview, but isn't optimal for digging down into an individual event. I wish you could set the window's time width or do a two finger zoom in/out.Occasional random readings happen during the night as you move/stir and that can be picked up by the software as events. For some, that may be the sort of data you want. For others, like myself, I wish I could "smooth" the data over several readings and make the report only show me odd readings more than say 5 or 10 seconds long to filter out random noise from single readings. A longer smoothing window might make the report of oxygen desaturation events more useful/reliable, in my opinion. Right now, I have to manually look at the longer term report and judge what is an event vs noise.The battery indicator on the display does indicate battery strength at full, 2/3, 1/3, 0 capacity, but you only see the display for the first 90 seconds of operation which is when batteries are typically still pumping strongly even if low. If the battery indicator is less than full, you probably won't record a full night.As best I can tell, the EMO-80 is available in a blue or a white color scheme, with no difference in function between the two, just different sale prices on Amazon. I like the product well enough but would buy whichever color scheme saves you $ at the time.

### ⭐⭐⭐⭐⭐ Finally a company that stands behind their product
*by S***D on July 8, 2022*

I bought this to compare with the pulse readings while daily checking Blood pressure using inflatable arm cuff. My doctor loves seeing the oxygen saturation levels as a bonus.Unit stopped working after about 7 months of use so I contacted them with a screenshot of my Amazon order and in a day they asked for my shipping address. Today, a week later, a brand new unit arrives in my postal box. Installed, one of the two sets of batteries provided and my first readings have been added to the previous readings in my account, seamlesslyHighly recommended, not only for the best online service I have ever encountered, but for a really high quality product that does what it is supposed to do and is simple to useAnd really, who in this day and age gives you an extra set of batteries !
