Everyone have to have one . Especially now days and now that winter is close Every House need to have this ....

feliz con mi oximetro.. llego a tiempo, y facil de usar . muy importante tenerlo en hogares .

When my family member thought COVID might be in them, they bought this oximeter that put their minds at rest. It is helpful in many conditions. I have used this professionally and personally for years.

I have heart palpatation issues and this comes in handy to monitor my heart rate It's also very useful when I exercise!

Works great! I don't always notice when I'm having an attack because it's less suddenly-can't-breathe and more a slow strangling of my lungs. I was on a trip recently and had a very bad reaction to the pollen there. It took me three days of struggling before I realized what was wrong. I know, what a dummy! But an oximeter would have helped so I got this one. It's perfect, exactly what I wanted, and it helps me monitor my heartrate for other conditions I have. :)
