Zacurate Pro Series 500DL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Silicon Cover, Batteries and Lanyard (Royal Black)

Easy to use

I liked everything about the item.

As a copd and heart patient, it is good to know these readings. Easy to use and read. Very pleased with this purchase.

Does exactly what it says it should.

No

This product was very easy to setup and use. Simply insert batteries, press the button and get your results. It shuts off itself, which is a nice function as well.

This device is easy to figure out, to use, to read and know the results of the test it performs and then to shut off. And the battery seems to last forever. Whats not to like? Handy and compact and handsome.

Easy to read and understand display for oxygen and heart rate

Exelente lo disfrutaré mucho
