## Description

desertcart.com: MDF Instruments, MD One Stainless Steel Stethoscope, Adult, Black Tube, Silver Chestpieces-Headset, MDF77711 : Industrial & Scientific

Review: Great product - I have has this for a few months now & it works quite well. The ear pieces are soft & has great sound. Not too much tension but enough to keep it in my ears perfectly.
Review: Love it - I bought this for my EMT course. It does seem to be well made and it's not too heavy. Lung and heart sounds are very clear. It doesn't hurt your ears as much as others I've tried, and it comes with extra ear bud sizes. If you're looking for a fairly cheap but good quality stethoscope for school, this is a good choice!

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐⭐ Love it
*by J***M on August 27, 2016*

I bought this for my EMT course. It does seem to be well made and it's not too heavy. Lung and heart sounds are very clear. It doesn't hurt your ears as much as others I've tried, and it comes with extra ear bud sizes. If you're looking for a fairly cheap but good quality stethoscope for school, this is a good choice!

### ⭐⭐⭐⭐ Just as good as the others
*by K***H on August 31, 2018*

At my job as an STNA I am constantly taking vitals and sometimes out automatic machines break. I am one of the few that know how to take a manual bp and the stethoscopes they provide are beyond cheap and don’t work. So i bought my own. I’ve used mainly Littmans when I borrow from my nurses, but what college student has that money. So I bought this one. It works just as good as the higher grade ones. I left out one star because I can hear the heartbeat more in one ear than the other, but that may be me. Overall great buy
