Review on EMAY Sleep Oxygen Monitor: Track Blood Oxygen Saturation & Heart Rate with App for iPhone & Android, Professional Report & 40-hour Memory by Brent Doolan

I wrote the review below, got a replacement pulse oximeter from Revain but still had problems with it. I was really frustrated and angry that I wasted my money (like I thought), tried twice, I was having problems all the time. Hence the review. HOWEVER I escalated the issue to their support department and this led to an exchange with them. I didn't expect them to be so responsive. But they were. I've addressed each issue below and they've answered them all. In one or two instances, the issue I raised was on my side; I did something wrong. In another case, the problem was that I misunderstood something. I think most people would misunderstand this, as would I, so I won't "own" this. They just need to be a little clearer in their instructions. In some cases the problem was/was on their side. And they were receptive to my very specific criticism, spoke to their engineers and computer gurus once or two and promised they would fix it. It was a long conversation with evidence that they took my concerns seriously. A gentle response drives away anger, the Bible says, and Emay did just that. They were open and accepted my anger, helped me understand what was wrong with me, and acknowledged their "part” in the issues I raised. The second pulse oximeter works much better now as some issues have been fixed. Having a working device and getting a great service response from the company makes it increasingly difficult for me NOT to love this product! I've raised the star rating to 4 (would have given it a 4.5 if possible) and will raise it to 5 once they make the adjustments we've discussed. ------ ---- ------------------------------ -I want to like this product but it will more and more difficult. First, the app I downloaded miscalculated my age. I had to enter an incorrect birth year to make the app reflect my real age. It's such a small thing to write code, isn't it? Why can't the code be written so that 2019 (when I got my first pulse oximeter from you) minus 1953 (my birth year) equals 66? I had to pretend my birth year was 1954 in order for my age to reflect correctly. By the way, why do you only have one year? According to your app, I'm technically 67 years old in 2020. But actually I won't be that old for 6 months. This is the real downside of your product. Second, the device doesn't stay paired with my iPhone and the required application. Getting a repeat link is often a problem. I hate struggling with the app/oximeter every time I use them not knowing if they will connect easily (and sometimes they do) or if they claim they can't see each other – although YES, my bluetooth *is* IN - Third, the second device I received from the company was unable to sync the internal date/time to the actual date/time via the app. So my first 3 hour reading has incorrect date information. Fourth, if the reading is the wrong date/time, you cannot go in and edit the result to reflect the correct date/time. Fifth. , the reading can be sent as a PDF file. which is nice. I did this and the file crashes in both Adobe Acrobat Reader and Adobe Acrobat Professional. Something is wrong with the way it was sent. Sixth, the first pulse oximeter they sent me was defective. He stopped recording for no reason. Then he "stuck" and didn't record at all. New batteries, turn off all devices (iPhone, app, pulse oximeter) and then restart. Nothing helped. I now have a spare oximeter, but I'm not sure if it's working properly. one had it, this one didn't. I like the heart rate printout. I like the fact that it records measurements every second. I like that I can set my own cutoff points for too high or too low. I love that recordings can be shared with the Health app on iPhone. But there is too much glitches in the oximeter and the app to make this a product I would recommend to anyone. Other issues with the Emay pulse oximeter (second device, sending the first one back for replacement): 1. Even though the device is connected to my phone's Bluetooth, the Emay app says it can't find my device to tell me how much time I still have on it. 2. When I turned on the device to allow the Emay application to read the remaining storage time, the device showed a message saying "Version 1.1" and then "Downloading in progress". However: (1) the app didn't actually download anything, and (2) the device is stuck in "downloading" mode and won't let me stop or even turn off the intended download. I have to take out the batteries to shut it down.3. The numeric readings from the device and the graph do not match the heart rate data very well. The reading might say my heart rate was 55, but the graph line barely hits 60 and doesn't even come close to 55. O2 data and heart rate data shown in the Emay app aren't getting "accurate" in exported to my iPhone's health app - as long as they are accurately recorded by the device itself! While uploading my O2 and HR info to the Emay app last night shows numerous and prolonged periods of O2 saturation dropping to 85%, there is no reading below 92 when the same set of up-to-the-minute data is uploaded to the Health app is exported to %!5. The Emay application gives you two options to save the generated report. One is to save it as an image; the other is to send it as a PDF. (As I've reported, their PDFs crash with both Adobe Acrobat Reader and Acrobat Professional.) Once you've decided to send an Emay report to yourself as a PDF, you can't go back and have it ALSO as an image to save . . I wanted to see what I would get with the image and not the faulty PDF but found that was not possible as once I selected the PDF option the option was lost for me.
