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

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!

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

Its works, its accurate and easy to use.

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

Bought this one for me during the height of the pandemic, and bought a different make and model for my mom, I tested both for a brief period, and both were within range of each other. This one is easier for seeing your stuff yourself.

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

Works as expected. Reasonably priced. Would recommend.

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

Works great, just as it should

Quality product
