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

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

Works as advertised.

This has worked well. Not much else to say.

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.

It’s sturdy and seems to work well.

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!

Works good....14 bucks, its a deal.

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

Works great, just as it should

Love this product. The Representative of a oxygen tank company at the hospital recommended this for my dad on Amazon and pulled up this model. My dad and mom like to use it to monitor their oxygen levels. It’s very small and lightweight. Great for on the go.
