NAR-S Pulse Oximeter

Used it during a night shift when I felt dizzy, and the numbers popped up in seconds on that clear display. The clip is snug without pinching, which I appreciate for quick checks between patients. Solid little monitor for peace of mind.

Took it on a hike and checked my oxygen at altitude—numbers showed up fast and held steady. The clip fits snug without pinching, and the simple button setup made it easy to cycle through the display. Solid little tool for peace of mind.

I've been testing mine against my doctor's office readings and it's spot on every time. The display is bright enough to read even in a dim room, which matters when I check it first thing in the morning.
