As a fitness enthusiast, blood oxygen monitoring is very important to me. This oximeter really helps me a lot. I measure my blood oxygen before and after every exercise to understand my physical condition. It is small and portable, and it doesn't matter whether I put it in my pocket or tie it on my wrist during exercise. And the data is accurate, which allows me to better adjust the intensity of exercise and avoid over-exercise.

Good product, very accurate.

A friend recommended me to buy this blood oximeter, which allows me to understand my physical condition in a timely manner and avoid major health problems.
