Pulse Oximeter Fingertip Oxygen Monitor Fingertip Pulse Ox Heart Rate and SpO2 Finger Pulse Oximeter for SpO2/Heart Rate/Perfusion Index Blood Oxygen Saturation Monitor with Battery Lanyard (Blue)

Works great. HR Seems to measure correctly when compared to bp machine. Can't speak to veracity of 02, but seems ok too.

Works great. Brought to doctors office and got the same reading that the nurse used. Accurate.

Works just like the doctor's Office. Only drawback is the screen does not right itself, up or down and wavy lines at the bottom, what does that represent? Other wise a very good purchase. Made in China...

I got diagnosed recently with severe persistent asthma and this has been a great purchase so far. I can monitor my oxygen levels anywhere ans it’s super portable and it’s so easy to use. Very accurate as I cross referenced it at my doctors appointment and it had the same results as the one they used. Great battery life. Screen is clear and bright and overall great quality for the price.

It's hard to read unless you put it on your right finger and you're supposed to put it on your left finger as the numbers are sideways and it's also not older people friendly the numbers are very small but it will do I should have paid attention my last one had big giant numbers and I didn't have to go get my glasses.

Works great helps me keep track of my oxygen level

Nice

Looks nice but when I tried it, I had to wait a long time for a reading. After about 10 seconds, as it was slowly responding, I gave up and shut it down. I use this for exercise, so who would want to wait for a response? I had another meterat the same time that took about a second to start the display and shoed everything fine( A Contec meter)
