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

Since I have asthma it's in my best interest to know my blood O2 percentage. It helps me decide if I can treat symptoms myself or need to call my doctor. I'm a little bit wary about it's accuracy, but that may just be me. At any rate I do trust it.

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.

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.

Directions are so tiny that you need a magnifying glass. Some quick start instructions would be helpful in a text readable by all ages.Accuracy is not great some readings take 1-2 minutes before you see a number.

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.

Easy to use and great to have your info quick without going to the doctor

Works better than I expected. I am very pleased.

It’s hard to tell which side is tracking the pulse and what side is tracking oxygen because they are both blinking. It feels like it’s hit or miss sometimes I can see oxygen number when it stops blinking.
