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

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.

Relatively comfortable to wear. Battery seems to run down quickly when I use it a lot, but the device has lasted a few years. Good reference measurements for health. If you’re looking for a little bit more coverage, I’d recommend a manual blood pressure cuff. It’s still possible to have high blood pressure with a low resting pulse

Opened the box, put in the batteries, worked like a charm.....the next day I was going for a Dr. Appointment....took my new pulse-ox with me, had the nurse take my o2 reading with her tester, and then used mine, and it was the EXACT same reading.....very pleased with product...

have a-fib used to monitor heart rate

Opened the box and took out everything and it was all there. Inserted the batteries and placed on my finger and presto. Worked like a charm.

This is great to have around, especially if you have asthma. Product is exactly as described and pictured. Its easy to use, takes 2 AAA batteries which are included. Also comes with a lanyard.

Works well Very simple Insert your finger and it instantly tells you your oxygen level

Great product!

Good price and product!

A good product. I would buy it again. Only drawback was it takes awhile to turn off.
