Pulse Oximeter, Fingertip Pulse Oximeter with Plethysmograph and Perfusion Index, Portable Blood Oxygen Saturation Monitor for Heart Rate and SpO2 Level, Large OLED Display Oximeter with Batteries

Product as described, easy to use, great price. Only "issue" - operating manual print so small unreadable. Was able to print one-off the internet. FYO - really don't need a manual. Pretty intuitive.

This thing really came in handy when I had bronchitis. It was very accurate based on the fact the numbers on the device at home was nearly the same as the one at the urgent care. I told the doctor what the device reading was at home and that's why I came in, she showed me the numbers and said that it's good I came in because my device was right. I highly recommend this unit.

Hard to read the numbers. The background color for the numbers is similar to the color of the light making it very hard to read. It works well and it is accurate. The battery has lasted this long with occasional use in the ER and other parts of the hospital. Just really hard to read. I'm gonna order a different pulse ox and throw this one away.

As a hospice nurse, most of my patients have poor circulation, cold fingers. I was unable to get readings from their fingers, & if I did, I couldn’t trust them. Though on warm fingers with good perfusion, it worked well. Unfortunately, I needed one that worked in cooler fingers. All in all good monitor for healthy adults.

Very reasonably priced unit. Great for ensuring your lungs are working if you might have Covid. Would definitely recommend.John Michael Huberty, Anoka Attorney

Is not accurate at all! It shows you good vitals even when your vitals are wayy bad. I checked my O2 and pulse before I went to see the doctor and it showed my O2 at 97 and my pulse at 82 but when doctor checked they checked it 3 times to make sure and my O2 was 88 and my pulse was at 141. Shows good vitals to make you think it actually works! But its way off!! So dangerous! Someone could die because of it! Thinking their vitals are good and they are over thinking rather than seeing they aren't and need medical help!!!!

bought this to keep a look out for low oxygen levels due to covid, this is very easy to use

Update: stopped working after 10 days. I guess you get what you pay for when buying the cheapest PulseOx on Amazon
