I have asthma. This oximeter helps me with my heart and oxygen measurements. To measure food I use an XOX scale.I use the oximeter several times a week. I recommend it.
Easy to use, with nice display. Very pleased with oximeter and fast delivery.
I had one before from a different manufacturer and it was ok but to read it you had to angle your finger a certain way. This one has about 4 to 5 ways to view the display. It seems very accurate and your results are very quick. Of course the initial reading is usually off a little but it doesn’t take long till you get to the correct one.
Works as intended, shipped promptly. Easy to use.
My cardiologist uses it.
