HEARTSURE Oximeter A320 Portable Pulse noninvasive and painless test that measures your oxygen saturation level, or the oxygen levels in your blood

Had this three weeks, very easy to use, easy to read large numbers on the screen and works well. No obvious downsides. Had this three weeks, very easy to use, easy to read large numbers on the screen and works well. No obvious downsides.

Well made and it certainly works well for people who don't have current respiratory symptoms.

Note for people who are using it for asthma - don't wait till the oxygen saturation drops before getting help. Well made and it certainly works well for people who don't have current respiratory symptoms.

Purchased the HEARTSURE A320 Pulse Oximeter in case needed for Covid. Checked it at Home and also we did a comparison test when at my Doctors - Both reading's were the same so all good.

I bought this Pulse Oximeter so that if we had a respiratory illness,for example COVID-19, we could check our blood oxygen level.
It seems to work well; we are both well at the moment! Good to have reassurance. I bought this Pulse Oximeter so that if we had a respiratory illness,for example COVID-19, we could check our blood oxygen level.

Great product. Works well and is reasonably comfortable. I like that I can choose the orientation of the display. Seems to be reading accurately for me and hubby.

I'm considering purchasing a second one in case two people are sick at the same time. You can never be too careful against this deadly disease.
