Belifu Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor for Pulse Rate and SpO2 Level, Portable Heart Rate Monitor with Large LED Display, with Batteries and Lanyard

I have actually lost count on the number of PulseOXs I have purchased for myself and family members since 2020. Of all of the different brands I have purchased this is by far my favorite. It is simple to use, provides the right information, offers feedback based upon the results, and auto shuts off. The only thing that could improve it would be if it were rechargeable - to solve that I use rechargeable batteries.

Compared well with my doctor's reading in office.

It’s so easy to use to monitor oxygen & pulse level whether working out or lying in bed ill, with a simple sleeve over your finger.

So cheap and don't feel it's good quality or accurate. Bummer.

I have a few pulse oximiters.First one a FaceLake FL-100 I like but it eats batteries even when not in use.Second one mystery made forgets settings and always beeps till I lower alarm settings+ eats batteries.Third one a FaceLake FL-400 bare bones single color good on batteries. Not easy to read(compared to others)Fourth one, the subject of this review, Belifu YM101 single color(red), good on batteries, and has perfusion index also.If you or someone you know uses an oximiter often this is a good choice IMneverHO!YMMV :-)EDIT: the picture does not match my unit, no idea what others reviewed but I reviewed Model:YM101Has red LED, easy to read, good on batteries

It works.

Really from worry when you’re congested you can actually read your percent of oxygen in your blood in real time and you can see when you take some deep breath’s in and blue body your mouth that the oxygen I will comes right up and then there is no worries if you have a cough and lung congestion if you’re getting enough oxygen
