SleepO2 Wrist Recording Pulse Oximeter by EMAY | Continuous Oxygen Monitor for SpO2 Tracking Overnight | Provides Sleep Report and Raw Data

Easy to setup. I downloaded the app to my tablet and phone. The device works well with the tablet. The tablet does not have to be on for the device to record. Comfortable at night and did not interfere with my sleep. I found the reports to be helpful and I saved the summary on one drive. The unit does need to be recharged after a night's use.

The device arrived well packed. The instructions are clear and well written. For context, I've been using the company's excellent finger pulse oximeter EMO-80 for seven months. It is a fine unit, and I expect the same tech is to be found in this device. I am only switching because, after trying many solutions, I have not found a reliable method to keep it on my finger during sleep! I've tried tape, tiny wedges etc., and finally a rubber band wrapped around it to increase grip. The rubber band generally kept the device on, but after a couple of hours, discomfort would wake me to change fingers. (As well, the EMO-80 is AAA battery powered, and two batteries are good for about two nights. Batteries are cheap these days but...) So finally, I'd had enough and ordered the SleepO2 Wrist Recording Pulse Oximeter. My only regret is that I didn't order it sooner! Another review mentioned annoyance, regarding the sensor and finger mount. Mentioned were discomfort, placement of the sensor, too much pressure on the finger tip, and that the blinking green light signaling the unit is operative (orange for charging) was too bright for the bedroom. First, about the light: I can't even see it, unless I raise the unit and look directly at it. I read the above-mentioned review before I bought the device, and was expecting something way different than what I got. I suppose different folks have different sensitivities to light, but this is about pinhead size, and isn't very bright. I've had no problems whatsoever with it. As well, the duckbill finger mount has been zero problem. I was surprised by how well it does work. Based on appearance, it might be a bit clumsy or awkward. I am an adult male, 6 feet tall, 180 pounds, so imagine my fingers in accordance. The finger easily slips right into the duckbill sensor mount. It isn't too tight or too loose, there's a comfortable pressure on my fingertip, and the sensor placement when using this oximeter seems fine. Basically, it just works. And whichever side you sleep, you won't need to make allowance. I've been surprised that it hasn't awakened me even once! I've become so accustomed that, on waking for a sip of water, I will check to see if it is still on my finger. The battery is charged by USB-3.0, so pretty quick. I haven't clocked charge time at various levels of discharge, but it isn't slow. And anyway, you've got a whole day before using it again! The box it comes in is a nice black cube and is fine for daytime storage. Connecting to the phone to download data is straightforward. Power up the Bluetooth on one device, then on the other. Occasionally, you might have to try syncing twice (It's Bluetooth, after all), but it will connect. With the data transferred to the phone, you can see multiple screens of graphs and information. There are many options for analysis, so if that's your thing, you can totally geek out. Printing the results is straightforward.Basically then, I have no complaints. Oh, wait! I did find the strap a little difficult to fasten, as it has a sort of peg that pops into a hole in the opposing strap. I've developed a technique and it's not so bad now. If you want to track your pulse and/or H02 levels, this is definitely the sweet spot in its price range, maybe even a in a higher one. Aside from the two niggling complaints – charging cable length and somewhat awkward strap fastening – I have no problems, only praise. I'm a fairly serious techie, and that's unusual. The oximeter does what it says it does, unobtrusively, and as far as I can tell, accurately. The readouts from both the finger pulse oximeter and the wrist oximeter are coherent, in that the levels and graphs are consistent. If you're wondering whether to go with the EMO-80 or the SleepO2 Wrist Recording Pulse Oximeter, I would say that if recording during sleep is your aim, definitely go with the wrist oximeter! I do not think you'll be disappointed.

I'm generally bad at following directions for unfamiliar tech devices...so I was very impressed at how simple & easy it was to set up and use this device. It's very comfortable to wear at night and works independently of the phone app. The device stores nightly data which you then sync with the phone app - then you can view the sleep data for each sesssion and generate detailed individual nightly reports. It's well designed and works flawlessly. I have "mild" sleep apnea and am using this to see the precise differences between sleeping with different apnea solutions - like a wedge pillow, sleeping in my recliner etc.

I’ve been using it a couple of weeks.Works reliably, the phone app is simple but sufficientThe finger sensor is a bit large, I’d prefer something smaller, but it stays on all night and it’s comfortable

I am generally very happy with the EMAY SleepO2 Wrist Recording Pulse Oximeter. It works works well, easy to use and the associated app provides a wealth of information, stats, reports and graphs to assess your overnight or episodic SpO2 and heart rate. Very useful for correlating the recorded info with the more general stats that might be provided for sleep by activity watches. My only complaints are design feature issues. The recording and transmitting unit, that straps to your wrist like a small watch, is very small and light weight. But the battery life is also very short at only about 10 hours. I would have gladly accepted the wrist unit being twice as large to get two or three times greater battery life. The micro USB socket for plugging in the finger tip sensor sleeve doubles as the charging port. That means you have to detach the sensor every time your charge the unit, which, as mentioned, is every day you use the device due to the limited battery life. I would have preferred that they had a port for the sensor and a port for charging. Also that the ports used USB-C not micro USB. And lastly the strap for holding the recording unit on your wrist is a plastic snap band, more like what you would see for a hospital ID tag, not a wristwatch band. I would have preferred a proper standard width watchband, and a replaceable one. All that said the info from the device is excellent and very useful.

I have been using this for 2 weeks now. At first I thought the fingertip plugged into this rubber device would bother me but within one night I got used to it. The little velcro wrapper could be a tad stronger, but that's easily replaceable.I love the two kinds of reports it provides. One is a 2-pager that you can share with your doctor, which is a summary of the min, max, average, etc. information with the number of drops. It also give heart rate and not just oxygen saturation.What was very important for me is that it reads every second! Most others don't! This is a huge feature over others especially at this reasonable price. It is very easy to use.The only slight inconvenience is that you need to recharge it every day, but it's a tradeoff I guess for it being able to measure every second, which takes more energy. Charging is easy enough, so no complains.
