Simple and easy to use. I brought it to my doctors appointment to verify that it was accurate, Right on.
I bought two, one rose gold and the other gold, both look great and seem to work perfectly!
I like the feature that allows you to read the numbers from a variety positions without having to read up side down and the green slide in the middle tells you that it is reading your pulse and O2. Measures quick and accurate.
No complaints - it?s as described. Easy to use and portable.
