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

Great Data and Easy to Use
This is an amazing machine–and a lot cheaper than most others. I’m not a computer expert, but I got it on and working quickly. Excellent instructions. It takes a whole night of almost second-by-second percent Oxygen and pulse data–and it stayed on my finger all night! You can then easily store all the data in your smart-phone. In addition to graphs showing highs, lows and percentages, you can scroll through the whole night and see what’s happening at any time for the whole 8 hours. I also tried it for a few hours during the daytime, and it stayed on and got good data whatever I was doing.

A product whose time has NOT come? Maybe not…!
I wrote the review below, got a replacement oximeter from Amazon, and still had problems with it. I was really intensely frustrated and angry at having wasted my money (I thought), tried twice, had ongoing problems…. Hence the review.HOWEVER, I communicated a question to their support department, and that led to an exchange with them. I didn’t expect them to be so responsive. But they were. I raised every single issue below, and they answered them all.In one or two cases, the problem I raised was on my end; I did something wrong.In another case, the problem was because I had not understood something correctly. I think most people would have misunderstood just as I did, so I’m not going to “own” that one. They’re just going to have to be a bit clearer in their instructions.In a couple of cases, the problem is/was on their end. And they were receptive to my very specific criticisms, discussing one or two with their engineers and computer gurus, and promising that they were going to fix it.This wasn’t a “brush-off” response from them. This was a sustained conversation with evidence that they were taking my issues seriously. A soft answer turns away wrath, the Bible says, and the folks at Emay have done exactly that. They were open and accepting of my irritation, helped me understand what I was missing, and owned their “share” of the issues I raised.The second oximeter is working much better, now that a few issues have been ironed out. Between having a functioning device and receiving the company’s excellent service response, I’m having a harder and harder time NOT liking this product!I’ve raised the number of stars to 4 (would give 4.5, if it were possible), and will raise it to 5 once they’ve made the adjustments we’ve discussed.———————————–I want to like this product, but it’s getting harder and harder.First, the downloaded app calculated my age incorrectly. I had to claim a fake birth year in order to get the app to reflect my actual age. This is such a small thing to write code for, isn’t it? Why can’t you write the code so that 2019 (when I received the first oximeter from you) minus 1953 (my birth year) equals 66? I had to pretend that my birth year was 1954, so that my age would be reflected properly.While you’re at it, why do you only have the year? Now, in 2020, I’m technically 67, according to your app. Yet in truth I won’t be that age for another 6 months. This is a real deficiency in your product.Second, the device doesn’t stay paired to my iPhone and the necessary app. Getting it to re-link is often a struggle. I hate having to fight the app/oximeter every time I use them, not knowing if they’re going to pair readily (and sometimes they do) or claim not to see each other—even though YES, my bluetooth *is* on!Third, the second device I received from the company failed to synchronize its internal date/time to the actual date/time via the app. So my first three-hour reading has the wrong date info on it.Fourth, if the wrong date or time gets put on a reading, you can’t go in and edit the result so that it reflects the correct date/time.Fifth, the reading can be sent out as a PDF file. Which is nice. I have done this, and the file crashes both Adobe Acrobat Reader as well as Adobe Acrobat Professional. Something about the way it’s sent out is faulty.Sixth, the first oximeter they sent me was defective. It would stop recording for no reason. Then it got “stuck” and wouldn’t record at all. New batteries, turning allllll devices (iPhone, app, oximeter) off and then rebooting…nothing worked. I now have a replacement in hand, but I’m not certain it’s going to function correctly, either.Seventh, the new, replacement oximeter is a different model than the first one–a few small-but-nice features that the first one had, this one doesn’t have.I like the heart rate print-out. I like the fact that it records a measurement every second. I like that I can specify my own cut-off points for too-high or too-low. I like the fact that the records can be shared with the iPhone’s “Health” app.But there are too many glitches in the oximeter and the app to make this a product I’d recommend to anyone.Further problems with the Emay pulse oximeter (second device, having sent the first one back for a replacement):1. Even though the device IS connected to my phone’s Bluetooth, the Emay app says it cannot find my device in order to tell me how much memory time I have left on it.2. When I turned on the device so that the Emay app could read the memory time left, the device said “Version 1.1” and then “Uploading.” However: (1) the app was not, in fact, uploading anything, and (2) the device is stuck on “Uploading” and will not allow me to stop the supposed upload nor even turn it off. I have to take the batteries out to get it to shut off.3. The numerical read-outs of the device and the graph do not match well on the heart rate data. The read-out may say my heart rate was 55, but the graph line barely strikes below the “60” mark and is not anywhere near the “55” mark.4. The O2 sat data and the heart rate data reflected in the Emay app are not exported to my iPhone’s Health app “accurately” – assuming that they are recorded accurately by the device itself! While the Emay app’s upload of my O2 and HR information from last night reveal numerous and lengthy periods of O2 sats dipping as low as 85%, when that same minute-by-minute data set is exported to the Health app, there isn’t a reading below 92%!5. The Emay app gives you two options for preserving the report it generates. One is to save it as an image; the other is to send it as a PDF. (As I’ve already reported, their PDF files crash both Adobe Acrobat Reader and Acrobat Professional.) Once you’ve decided to send the Emay report to yourself as a PDF, you cannot go back and ALSO choose to save it as an image. I wanted to see what I’d get with an image rather than the buggy PDF, but found that I couldn’t because the option was lost to me once I’d chosen the PDF option.

Many features & Accurate
This pulse oximeter does everything it says. I really like that it works with an app and I am able to track my usage and results on a nightly basis. The reports help my doctor to adjust my oxygen needs. It’s very user friendly, works flawlessly and is accurate! I highly recommend this pulse oximeter.

Semplice da utilizzare, di buona fattura. Buona anche la app a supporto.

good product, works well, the phone app was easy to use and I’m satisfied with it
