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

I Like it. Lightweight, Simple to use. Came with batteries. The screen is easy to read and automatically rotates so you can read it no matter how you want to hold your hand. The user manual is not the greatest (sections zig-zag down the page from the right side to the left side. Looks like it was laid out to be a booklet but then printed on a single sheet) But you don't need the user manual to use this, it's just that simple.
