Review on Pulse Oximeter Fingertip: Digital Blood Oxygen Saturation Monitor For Heart Rate & SpO2 Level Monitoring - Portable LCD Pulse Oximeter With Batteries Included by Matthew Sytniak

This pulse oximeter came quickly and was a great price. It arrived neatly and safely packaged in a small box. After opening it, I found the directions placed right on top, which were incredibly easy to follow and understand. Next, came the pulse oximeter, which had a layer of film protecting the lcd screen. New batteries were located below the pulse oximeter. I literally installed the batteries and it was ready to go. You place it on your finger, press the button, and let it do the work. I think it got a super accurate reading within 5-10 seconds.
