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

It’s sturdy and seems to work well.

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

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

Bought just to have available for potential future illness. Since they’re so cheap these days it seems like a good idea to keep at home next to the thermometer. As far as I can tell it appears accurate. I get the same pulse measurement when I take my pulse manually. I do recommend giving the pulse reading a minute or two after you start the device before you trust it. It does seem to need a moment to read your pulse before it becomes accurate, which I guess makes sense. Can’t speak to the accuracy of the oxygen reading since I don’t have anything to compare it against except to say the reading indicates my blood oxygen is normal and I’m currently not ill.

As an asthmatic, knowing my O2 stats is incredibly important to keeping myself in good health. This product is small, easy to turn on and use, and works quickly. It can be a bit finicky if you dont get your finger placed correctly inside the unit, but you will get the hang of using it pretty quickly correctly. Overall the device provides good quality and an easy to use O2 reading.

Excellent

Works as expected. Reasonably priced. Would recommend.

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!

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