★★★★★

Paughnee White

So easy and convenient. Allows you to test at home in the comfort of your own bed without all the wires and monitors of outpatient studies. Highly recommend

★★★★

do not make the band holding on the sensor too tight.

★★★

Pamela Brown

can not be measuring many factors as I did a home study about 15 years ago and it seemed to measure so much more. As the test I did 15 years ago was only measuring some of the main features. This is measuring my left index finger only. so what is this a O2 sensor and measure my pulse, I do not think this can be as accurate, oh I guess I'll see?
