With a decent enough price that many students in medical school or practicing to be a nurse have purchased this stethoscope and find they are able to hear significantly better than their fellow students.

There are very few available complaints about this model. One customer found it worked impeccably, but the smaller side broke after 1-2 years. The replacement also broke after a period of time.

The only person to deliver a rating of less than 3/5 stars complained that one of the stethoscope arms broke in half upon the first use. Littmann was, however, quick to replace it.

Besides those who received stethoscopes with minor defects, the only reason consumers rated the Littmann Cardiology 3 Stethoscope below 5/5 stars is because they found other models slightly more effective, however more expensive. There are no complaints about the clarity or actual performance of the stethoscope.
