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

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

Works as advertised.

Works Great! Thanks!

Great product!

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!

I bought this pulse oximeter after my doctor asked (remotely) what my blood oxygen level was. It arrived quickly and has performed flawlessly. Great price, too, in my opinion!

Quality product

Easy to use and read.
