Fingertip Pulse Oximeter with Plethysmograph and Perfusion Index, include carrying case, Large OLED Digital Display Blood Oxygen Saturation Monitor Heart Rate Monitor (Color: Red-Orange)

Works well, no complaints. I’m a stroke survivor and I’m able to use it easily.

I've had this for some months now, and it has been flawless, accurate and reliable. Batteries have lasted as well.

It cost a bit--but it is accurat. Reading can be obtained even when patient is not still--during a seizure.

Screen orientation cannot be changed. Very annoying.

Works very well. I am very happy with it. The huge plus is the perfusion index reading, which indicates how well your arteries and capillaries function. The pulse display is very good, showing the width of the decline in flow between pulses. This narrows with Atherosclerosis, aka hardening of the arteries, which also affects the Perfusion Index. (I buy L-Lysine from Amazon. Do some research on Atherosclerosis and Lysine.) The display is a bit small and does not orient to "down", but so what, you get Perfusion Index and that is very, very important. I did a Science Fair project and demonstrated this kind of stuff to a number of high school science classes of my fellow students and teaches many decades ago. I got to see how age affects arterial elasticity. Before microelectronics, the equipment was "bigger than a breadbox" and expensive. Science is FUN! At least it is if you look for principles instead of trying to memorize facts.

Works even on hard to read thin fingers.

This Item is the greatest, it reads quickly, and is very easy to use, When I visit the doctors, I always take it, most nurses love it. It also stores the data.
