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

Exelente lo disfrutaré mucho

Easy to use and seems accurate. Helpful to keep track of oxygen level.

A simple concept well executed. The display direction works for both left and right handed use... one would expect that this goes without saying, but there are other pulse oximeters that either have a fixed display which can be read only when clipped to the right hand index finger, or come with a button to flip the display for use on the left hand.

Works great. Went to DR appt and compared with theirs and same out come

I compared my readings with this Zacurate oxygen saturation device, with the readings at my nurse practioners office just two days ago, and they matched exactly! So easy to use, too! I can see why there are so many 5-star reviews!

I am using the Zacurate Pro Series 500DL Fingertip Pulse Oximeter Blood Oxygen a lot. It works really amazing and is easy to understand and use. Thanks.

Easy to use and read.

Exactly as expected

That it works well
