WOWZERS! I can’t say enough GREAT things about this stethoscope!!!! It’s AHHH-MAZING! Everyone at work is blown away by the sound and noise cancellation features. I literally have to pick their mouth up off the floor from being in AWEEEEE after listening with it! I purchased an AirTag to place on it to keep track of my new toy! My one night-shift Dr calls me when he has some really cool heart/lung sounds to listen to! 🩺👩🏻⚕️🫶🏼
