Works. Unbeatable price.
I now have 3 different models of these. This one seems to agree with the other two for pulse rate and oxygen level. It works easily and quickly, is plenty bright, and was half the price of my last two.

Decent and functional for the price
Included Lanyard and 2 X AAA Batteries tailored for this fingertip pulse oximeter. Decent and functional, but has a few minor drawbacks I purchased this fingertip pulse oximeter to keep track of my oxygen levels and heart rate. Overall, it gets the job done, but it is not perfect. What I liked was that it has a clear display: The OLED screen is bright and very easy to read. It came with the lanyard and 2 AAA batteries, so I could use it right out of the box. Fast reading: It works great, the SpO2 and pulse readings show up quickly. It is a solid, average product for the price.

Price is right
I purchased two of these one for at home and one for Cottage. They are literally lifesavers. Quick and easy to use with a nice display. I would highly recommend these people that have heart issues.

Accurate, Easy to Use
Now that I am on supplemental oxygen for my COPD, it helps to have a pulse oximeter nearby wherever I am so I can keep tabs on my breathing. I ordered this to keep on my nightstand, and it has been doing great. Being the skeptic I am about anything I buy online, I checked it against the other two I have, and it is just as accurate. The price was more than 75% cheaper than the one I bought last year with my insurance OTC benefits.

Teuer aber relativ genau und gute Ablesbarkeit
Zum Vergleich mit Brustgurt und anderen Geräten ist die Genauigkeit gegeben. Anwendung sehr einfach und man kann die Zahlen sehr gut ablesen.
