### ⭐⭐⭐⭐⭐ Sweet stethoscope
*by A***M on February 4, 2020*

The built in lcd clock is a killer feature. I haven't found another stethoscope with one. It's silent so you don't hear ticking. I can hear much better with it than my old Littman, costs less too

### ⭐⭐⭐⭐⭐ Great Stethescope
*by K***R on September 16, 2023*

Good quality stethescope. I can hear through it even with noisy background. Good weight but not too heavy.

### ⭐⭐⭐⭐ The Stethoscope is Fine; The Watch Less So
*by A***R on July 2, 2023*

The watch did not work. However, MDF stood behind their lifetime warranty, and sent 2(!) replacements and fresh batteries. The watch is still disappointing cheap quality. The stethoscope works fine, if you can live with having only an adult diaphragm head — probably, if you’re just doing blood pressures and rudimentary auscultation of lung and heart sounds. Quality is OK, but overall, I would recommend saving money and purchasing a conventional stethoscope instead. The watch just isn’t worth it. MDF makes good value instruments, but this isn’t one of them. That said, their warranty service is excellent.
