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

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.

Had for 2 weeks. Very easy to use. Just stick your finger in, push the button and wait a few seconds.

It’s sturdy and seems to work well.

Does just like it’s suppose to. Great addition for any med kit.

there were instructions for easy use. Batteries were included.

Easy to use

it appears to work better then the one my nurse had.

Checking my blood oxygen.

We ordered this so we can better track our respiratory/heart health. What a great device and it works wonderfully; exactly what we needed. Thank you for shipping it so quickly! It arrived in great shape.

I have only been able to get an accurate reading on my little finger. Perhaps because other fingers are a little bit calloused with age? It also seems a little slow at calculating. But not bad for $20. Just dont get too upset if your reading is too low. Try other fingers before calling 911!
