Editor's Pick: If you have elderly family members at home or just want to keep an eye on your blood oxygen during workouts, simply clip it on your index finger and the reading appears on screen within seconds. The black shell is compact, so it fits easily on a nightstand or in a carry-on bag without taking up space. The display font is large enough to read clearly even without turning on the lights at night.
