This unit is easy to use, turns itself off and, comes with a Carrier case. I made a good choice here.
Price, easy to use.
Easy to use and accurate enough. I use it at home to keep an eye on my Oxygen levels due to pulmonary involvement from an autoimmune disorder. It’s not intended to diagnose any medical condition but it does help me track my progression without constantly going to doctors.
Works great. Beautiful oled screen. Screen changes orientation when turned vertically or horizontally.
