It is recommended that users consult a licensed healthcare provider or professional on how to interpret user readings based on physical traits or characteristics.

Accurate, easy to read, works phenomenally well
This was easy to use, and very accurate when comparing to my Drs pulse oximeter. You do NEED warm hands or the pulse oxygen will be off, but this is standard with these devices. It comes with a carrying case and batteries! Excellent value and functionality.

Great health gadget works perfect.
Great little health gadget. Very visible digits. Fast reading. Very accurate. 5 stars
Alyssa Higgs –
Very accurate and easy to use.
I compared it to my doctor’s pulse oximeter and it was very accurate. I love that it actually shows your heartbeat line instead of just the beats per minute. The screen turns depending on the angle of your hand, so no matter which way it is, you can read it. The screen is a good size to be able to see all the information easily. It is comfortable to wear.

It works well!
I bought this to check my mother’s spo2 levels quickly since she has moments where it goes down out of the blue. Its about the same size as the rest of the others out there. It reads quick, seems accurate and has a handy strap for the neck that is easy to disconnect it from if you need to grab it fast. The color is also really cute!

Good item and cost effective
This is a great thing to have at home or the office, especially if you’re worried about oxygen saturation when you’re sick (or not). It also shows your pulse pretty accurately. Great item for the cost.

Easy to Use, Reads Quickly
With upper respiratory bugs going around including COVID, RSV and influenza, this is a must-have device for checking oxygen saturation levels.It’s quick and easy to use, taking maybe seven seconds for the readings to appear.With the low cost of this item, it should be as common to keep on hand as a fever thermometer is. Both items will help you decide when it’s time to seek medical advice for an illness.The back battery cover is simple to remove and fortunately takes two AAA cell batteries – not expensive button cells.Overall, it’s a great value for the price and function.

Definitely worth the price! Better than expected!
Works great and is accurate at a great price.

Fast readings
Bought for the color to match the rest of my nursing equipment. Faster readings than my employers pulse ox readers. Works perfectly

Sirve muy bien, muy económico, con el tiempo y uso constante se debilita el resorte, pero nada que no se pueda solucionar
