Rechargeable Fingertip Blood Oxygen Monitor P R and PSo2 for home fitness, alpine area, sports

There were no instructions on how to make this work. Can take real time oxy reading, but still haven't figured out how to take an overnight reading.

Great to use with exercise.

This is a great product. A little hard to read the fine print but the optional functions are nice. Unfortunately the included AAA batteries arrived DOA. But we had some on hand.

Love the alarm when it gets a low reading and it uses AAA BATTERY

Excelente muy bueno

Better than the one they use at the hospital very accurate

I’ve had it about a week, I love it. I love the feature that allows you to set it to alarm at your preferences. Great features

Very easy to use. Several different displays.
