LOOKEERing-Pro Wearable Oxygen Monitor with Vibration Reminder for Low O2 - Continuous Pulse Oximeter -Rechargeable Blood Oxygen Saturation Tracker for SpO2 & PR - Free APP & PC Reports

It took me awhile to figure out what finger to use and the best spot to attach it to. In result, the most accurate reading I get is when I attach it to the tip of my middle finger or thumb. Overall, it is more comfortable fit for me for the overnight wear when I use my middle finger with device taped for extra security so it doesn't come off when I move in my sleep.I find this device more ACCURATE than some other brands that I have tried, battery life is plenty, it FITS GREAT for overnight wear with some taping, the ALARM function is simply AWESOME and the main reason I bought it in the first place (I had afib event w. a trip to the hosp recently due to hypoxemia... now I am reminded to breath at night now and then).Personally, I am going with the extended 3y warranty as some people complained about device quality, which probably makes sense if it is used daily.

This is a must if you use oxygen at night. It will vibrate and wake you up when your oxygen level drops below 90. I had Covid 19, and it affected my lungs. My oxygen level would drop below 90, and this was a life saver.

This works very well for monitoring sleep apnea. And it buzzes when your oxygen level drops too low. I use it every night with my cpap mask. It also checks for A-fib.

Who knows what goes on while you sleep? Well, this little thing let's you know how you're doing . . .

I ordered this to track and alert me when o2 sats dropped below level. Work the first two nights then it turned off due to placement of button and fingers when sleeping the next two. Does no good if it keeps turning off. Plus readings were not same as on other two comparison oximeter. Read much lower (5 or more percent)

Wish I could give one star. I took to my Dr and it is off by 7% with multiple trials. Sometimes more. You can’t trust it and I am a PhD Nurse Educator who has used similar products. This is dangerous. You need to sleep with your arm resting on a pillow so it’s elevated, if your hand goes down it drops dramatically, oxygen doesn’t work like that. It doesn’t go down 8% because you turn over or adjust your hand. States no refunds when you try to return. It’s not just useless it’s dangerous for someone counting on it and if you are paying this much you are counting on some accuracy.

I've been using it almost every night since shortly after I was put on the Cpap. I wanted to know if it was helping me. My first appointment they said I was doing great. Low and behold, the Lookee O2 monitor proved different. I learned ir I slept on my back, my O2 would go below 80. If I sleep inclined, it stays above 90. This helped me learn what my best sleeping position is. I have compared it numerous times with my O2 finger sensor. It may be off 1 or 2%. Just make sure the monitor power button is rotated away from your finger so it doesn't get turned off when you're sleeping. I have woken up from low O2 and put the finger monitor on just to verify and it too says it was low. If you're missing a download to your phone, turn it off and back on and it will finish downloading your missing hours. I am satisfied with the unit.

This device consistently reads my O2 saturation 4 to 5 percentage points below ANY reading I've EVER seen in my doctor's office. When comparing O2 saturation in real time against another device ( https://www.amazon.com/gp/product/B077ZJ1ZKZ ), this LOOKEE device consistently measures 4 to 5 percentage points below that device. I have ZERO confidence in the accuracy of this device with respect to O2 saturation (the pulse reading seems accurate). Sending it back for a refund.
