WRINERY Fingertip Pulse Oximeter, Oxygen Saturation Monitor, O2 Saturation Monitor, OLED Portable Oximetry with Batteries, Lanyard (Gray-White)

very nice.

I bought this so I can check my baseline oxygen saturation in this pandemic we are in, since I had momentary covid scare when I thought I was starting to exhibit symptoms with fatigue and shortness of breath. Took a covid test and turns out I was NOT positive for coronavirus. The price was right and it's packaged with a small carabiner hook and carry case. The pulse rate was very accurate as it matched what my fitbit watch was measuring. I like the other metric where it shows your perfusion index (PI) which is your pulse strength...from this you can determine which finger is giving you the best pulse output level for reading O2% saturation. The OLED screen is easy to read! Was able to use my HSA account to pay for this tax free. Thanks again amazon!

Excelente producto....

Works great. Not a fan of the sound it makes.

Easy to read

Very good quality, is dependable, ( my cardiologist checked its efficiency) and it goes with me everywhere since my first A-Fib episode.

I have bought several I'll be over the last two years. I've been at the ER nurse for so so many years. And have worked a variety of settings. I don't know what a respiratory therapist would say about it but seems to give pretty solid readings which is aided by the plethysmograph. Perfusion index reading even the respiratory rate with the right patient and spot on. Like all of them they it helps to have no fingernail polish and out also depends on their overall status and life excetera. But I will tell you I would recommend this over and over and over again I bought them for my kid and many of his friends who are in med school. And frankly you just can't beat the price I mean I can't believe these are only $25. This is a fair price for a fairly solid quality product and the case that comes with it who were the five bucks alone. The comments like this I hope the price doesn't go up.

A key feature that I need as a volunteer EMT is the ability to change the screen orientation depending how the patient presents. Almost every model I have purchased can do this-note there is no mention of the in the written instructions BUT a search on the 'net says that this model CAN do that by pressing the power button once while it is taking a reading. Apparently either this model CAN'T change orientation OR mine is defective which makes it mostly useless for my needs.......If I am a numpty and someone has figured this out on THIS model please let me know!
