This product does not emit very much light of its own, and is not intended to be used as a light source. Therefore, my standard review format will not be used and the product will not be assigned a rating.
The Choicemmed Oxywatch C20 Pulse Oximeter is a small, discreet device designed to measure your SpO2 (blood oxygen saturation) expressed as a percentage value by simply clipping it to your fingertip. It also measures your pulse (heartbeats per minute).
It operates from a pair of AAA cells, and has an OLED (organic light-emitting diode) display.
To use your spiffy new Choicemmed Oxywatch C20 Pulse Oximeter, simply squeeze the unit on the end opposite the black power pushbutton, slip your finger in, and gently release.
Press & release the black pushbutton. If necessary, press & release it one or more times until the display is rightside-up.
Within several seconds, the unit will display your SpO2 and your pulse.
Once the product is removed from your finger, it will turn itself off after approx. ten seconds.
To change the batteries in your Choicemmed Oxywatch C20 Pulse Oximeter, turn it upside-down, slide the battery door off in the direction of the embossed arrow, and set it aside.
If necessary, remove and dispose of or recycle the two used AAA cells as you see fit.
Install two new AAA cells, orienting them so that their flat-ends (-) negatives face the spring for them in each compartment.
Slide the battery door back on, and be done with it.

You can also see where I pushed the button on its front that causes the display axis to rotate in 90° increments.
