Super simple to navigate. Just clip it on, press the button, and wait for your results. Easy!

My father only speaks Chinese, and when I'm not around to help him he is able to change the language settings and use it on himself. Cool idea!

Very easy to use and important to have on hand for my illness.

I use this in my practice and it has never let me down! This is a very reliable and useful tool that provides consistently accurate results.

Was able to use this on my pediatric patients because it comes with a child size clip.
