Customers find the blood oxygen monitor easy to use, particularly for elderly users, and appreciate its value for money as an inexpensive health monitoring tool. The device measures oxygen levels effectively, with one customer noting it instantly displays pulse rate and oxygen levels. Functionality, accuracy, and readability receive mixed feedback – while some find it reasonably accurate and fast, others report inaccurate readings and slower response times. Durability is also mixed, with some describing it as well-made while others report it breaking within weeks of use.

Great deal for what I needed
This pulse ox has gotten a reading when my high end unit would not. Weird but if it works it works. Fits nicely. Works as it should. Allows you to clip the display and change the orientation as well. Large lettering allows quick and easy reading of values. Nice lanyard to keep track of it.

Good
I really love the color, and it comes with a storage bag. It works just as you’d expect, its lightweight, and easy to read the results on the display. It even comes with batteries.

Accurage and easy to read
As a nurse practitioner I have used a lot of oximeters, and by far, this is my favorite. The readings seem to be more accurate and even read when a patient has cold hands/fingers. The light on the display is bright enough to make it easier to read. The numbers are large, which also aids in making it more user friendly. Comes with a case, and a lanyard so that you can wear it around your neck.

Works great
Works as intended, does not work for my 5 year old who’s finger is smaller. But works great for the rest of the family and we love it for a peace of mind when sick.

Pulse and Oxygen Reader
I love this because it measures both your heart rate and your blood oxygen levels. It’s very reasonably price and is something I would recommend!

Out $11.
I first bought this in 2020 during the height of Covid when there were so many scary stories about dropping oxygen levels. I wanted to check! This was inexpensive and came quickly. I now have a health issue where my doctor wants me to check pulse and oxygen daily so I was glad I had this. It’s the same brand the doctor uses. After four years it just began having issues. It turns on when I insert my finger, but then after a few seconds it just goes blank and displays no data. Since it still had the original batteries I decided to replace them. But even with new batteries it still just shuts off without displaying data after a few seconds. Still, it worked perfectly for four years, and the price is right, so I just decided to order it again.EDIT: new one arrived and it’s defective. Gives crazy and inaccurate readings like saying my O2 level is 77 to 80%. Clearly wrong since I feel perfectly fine and my Apple Watch says my O2 level is 97%. I can’t even return it since return details say it must be placed in it’s original packing materials, which I no longer have. Oh well. At least it’s cheap but I guess I’m out $11. I was happy with my first one for four years but if I buy another it won’t be this brand.
