Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor Pulse Ox, Heart Rate and Fast Spo2 Reading Oxygen Meter with OLED Screen Included Lanyard and 2 X AAA Batteries

It’s super straightforward to use—just clip it on your finger, and you get an accurate reading in seconds. It works great, and I use it all the time at work. Plus, it’s incredibly affordable for the price, especially considering how reliable and easy it is. Highly recommend!

Love this thing, it gives an easy way to measure heart rate and oxigen level. The display is just what I like, easy to read and showing the rhythm without beep beep sounds. Comfort to carry around. Love the color too.

Inexpensive and works right!Greatest display size. Seems accurate.

I carry 4 of these in several different medical kits, it is just a tool to send you in the right direction of helping a Pt. I don't live by these because there are so many variables associated with checking O2 saturation, but this does have a perfusion meter and wave form which helps decent product.

Happy with oxygen sensor. Old one didn't measure right.

With its compact size and lightweight cabin, it is a portable companion that I can just take with me wherever I go. The clever addition of straps ensures easy access to the product at all times by keeping it tucked around my neck at all times. My oxygen saturation level and heart rate are displayed on the OLED screen in a clear and transparent manner, which is an outstanding quality even for people unfamiliar with a lot of medical jargon. Real-time data is provided in a way that easy to understand so gratitude is expressed in a natural way Provides accurate visuals in seconds and allows me to instantly monitor changes in my blood oxygen levels. I was pleased that the fingertip pulse oximeter gave results that were more in line with professional measurements when I compared its readings to those taken at my doctor's office and I'm comfortable using it as a tool for control despite my overall health due to how accurate the machine is always. Because it comes with two AAA batteries, I was able to start using the pulse oximeter as soon as I took it out of the packaging. This is a very useful feature provided. Additionally, the device’s energy-saving features assure long battery life, making it a practical and cost-effective option to consider.

This is a bit slow but very accurate. I take it with me everywhere I go. Very convenient.

Odd - I have had a few of these and this one seems to not want to work in direct sunlight. I tried it with the included batteries and it reads "Finger out" and turns off. I tried with fresh Duracells and it reads "low battery" then turns off.I went indoors and was packing it up to send it back and tried it again with the included batteries (AAA) and it started working. Went back outside and "finger out" popped up again. So, it's very light sensitive.I went back inside and tried the Duracells. Still showed "low battery" even thought they tested fine in a voltmeter. So, there is something about either the fit or the output of the factory batteries that tells me once the supplied ones are dead, the whole device is dead. Perhaps lithium versions would drive it.It also does not have any orientation options. My others will rotate with each button push so you can read it rightside up regardlass of your position. This one only has a single display orientation.There is a menu where you can alter the brightness and the 10 second auto off feature is nice but off the three I own, this is the lowest rated. Head to head with the others (one on each finger) it is +/- 2 on all readings, so roughly the same accuracy. I would have sent it back, but this is one that requires you to print and box unless you go to Whole Foods and that drive would cost me more than the device is worth.
