Bests & Worsts Reviews from Amazon

This piece looks good, no doubt. Lots of compliments. But do you want to look good or do you want it to work? I could be auscultating apical for 15 seconds, then all of a sudden, I lose the sound? (no, my patient didn't die)! I'm wondering if it's not the earpieces actually getting too tight inside my ear canal and blocking sound? Try to auscultate lungs... nope, blank. Try to auscultate carotid? nadda. I've had to borrow someone else's because this one just wasn't cutting it!
