Pulse Oximeter, Blood Oxygen Meter, Fingertip Pulse Oximeter, Rechargeable Pulse Oximeter, Accurate Rapid Blood Oximeter SpO2 Reading Outdoor Sports Wide Use （black）

I have a number of these oximeters. This one is my favorite to take to the gym. It works great for dialing in the cardio machine settings to hit those target heart rate zones. It's also helpful to check on your BPM and O2 levels between lifting sets. The basic LED display makes the battery last a very long time. I'm talking weeks. I love that it is rechargeable with USB-C and that it came with a little clamshell case to help protect it in my gym bag. I tried a very popular $10 oximeter, but using how I want in the gym, I was changing the 3 AAA batteries every few days.

It works perfect and it is very accurate

Sometimes it takes a while to read and you have to remove it and place on another finger, but it works well, even when jogging.

Item was exactly as described. Accurate and fast readings. Comes with a case and a charger.

I love this rechargeable pulse oximeter. It fits my tiny fingers perfectly & the speed & accuracy make its functionality perfect.

Very compact and I like that you don’t have to search for the on/off button, just put it on your finger and it begins to read the data right away.

Este producto no marca la oxigenación en sangre (%SpO2) de forma correcta

This unit reads accurately. It's size and compact case are handy to transport. I wish it were easier to pinch open without having to use my other hand to hold it open for finger insertion. Otherwise, it's a very good product. Being rechargable was the biggest selling point.
