Zacurate FSA/HSA Eligible 500E-B Wireless Bluetooth Fingertip Blood Pulse Oximeter Monitor with FREE App, SpO2, Heart Rate, Plethysmograph, and Perfusion Index Finger Oxygen Sensor Meter

This unit is extremely well-built, comes with a case and protective cover, and lanyard. It synced instantly with my iPhone, so that bit integrates smoothly with Apple Health. There is no indication in the instructions about where to download the App that is required for phone integration. Once found, and opened, the results are immediately recognized by Apple Health. My doctor recommended that I have one. This is perfect for my needs and setup was fast and smooth.

Arrived right on time, work’s great!

Arrived on time in perfect condition. Had excellent feedback comments. I was a little wary as it was under $12. bucks to my door. I recently took this to my pulmonary walking test and compared numbers to the hospital's state of the art device. The pulse was the same throughout the walking test. The saturation number was low, BUT consistently by 3 points...so now I know accurately what my oxygen saturation is simply by adding 3 points. If you need such a "tool", get this one. Come with a protective woven nylon case so it's safe to throw in my backpack. buy without hesitation.

Very sensitive works good

Good movie

Easy to use

Disappointed

I primarily bought this to record SpO2 over some amount of time. However, as soon as I close the App, recording stops. Also, the App requires you to register and generally is cumbersome to use. 3 starts because it does fulfill its primary purpose of measuring SpO2 and displaying it. If you don't intend to use this with you smartphone, it seems to be a good device.
