Dangerously inaccurate and inconsistent according to Mayo Hospital Emergency doctor
I just spent hours and a fortune at Mayo Clinic Hospital in part because this oximeter gave low and erratic results. They recommended replacing mine after a side-by-side comparison with theirs on my hand.
I replaced it with Walgreens brand in-store at Mayo's recommendation which has proved flawless in repeat Mayo Hospital side-by-side comparison today.
