Pulse Oximeter Fingertip-HOLFENRY Oximeter Blood Oxygen Saturation Monitor spo2 Pulse Oximeter Finger, for Heart Rate Sat% Oxygen Saturation PI

I purchased this as a replacement for another Bluetooth monitor I lost somewhere. I have AFib, and quick periodic monitoring of my heart rate is helpful. Cellphone apps where one holds a finger over the camera were simply not accurate. This one combines old-fashioned technology with an app that measures and then tracks the data in the iPhone health app.

⭐️⭐️⭐️⭐️ The oximeter works well and gives quick readings for both oxygen and heart rate. The Bluetooth feature is a nice extra, although sometimes a bit slow to connect. Overall, it’s reliable and convenient for regular checks.

Works well. Easy to read. Reliable

This is really an item that needs to be in every home. It's function is so important, and particularly after the pandemic, these have become invaluable in terms of helping predict when there is a medical problem, and when there is a potential for one. This pocket oximeter is so small, and fits on the tip of your finger. It's got an awesome, easy to read red LED readout that is large, and very legible. It's also very fast. Completely intuitive to operate (one-button operation), it gives you the reading fast, allowing you to set a baseline, and continue to monitor. Takes two AAA batteries (included), I keep them out of the unit when not in use. In this way they last a long time, and they won't leak. A great product, and a super deal. I really am surprised that there isn't one in every home. There should be.

_When exercise it’s helpful sometime to know some of your vitals so that you can adjust acordingly. The “HOLFENRY_Fingertip Pulse Oximeter for Adult, Measuring SpO2/Pulse Rate/PI_Multi-function Oximeter-oximeter can measure multiple parameters such as Spo2/perfusion index (PI)/heart rate at the same time” will provided some of the information in real time. However, the color of the display is very hard to read-red font in a black back ground. The battery compartment apparently not design for human hand to insert the AAA batteries- you have to going sideways then force. --

Great tool to have around as oxygen saturation is a useful early indicator for numerous medical issues. It works by averaging out multiple results allowing for decent accuracy. This particular model is a bit dated, requiring AAA batteries while new types are USB rechargeable and offer app integration, though that's perhaps better for older users.

For some reason, I love testing oximeters, just call me strange. Let's see what we have here.. Accuracy. I compared this to my old one as well as to one that I know measures far too low. It matched up with my old one which I know is accurate so I want to confirm that this one here is accurate. Batteries. This comes with two AAA batteries included. The battery compartment is very easy to open and close. One thing I want to mention here though, after initially putting the batteries in, it showed that my pulse was 14. I'd not be alive to write this review if this were the case. I had to turn it on a couple of times, and then it started to measure accurately so it might not hurt to turn it on a couple times just to be sure. Instructions. This comes with clearly written instructions that are easy to read and follow.

A very useful device to know and check into your vitals. It's compact and easy to use. Light enough. Battery operated.
