Very nice oximeter; 5/5, I’m a pulmonary physician, I’m pleased; it’s a keeper. -professional, comparable to high end pulse oximeter -accurate, O2Sat value, heart rate, and wave forms, I have calibrated against my baseline, at the medical center. It’s accurate. -easy to use -I bought another for my sister— I’d buy again. -Comes with sleeve, case, batteries, strap, instructions. I’d buy another for a family or friend.
