Watch out Littmann, MDF is coming for you!
The past two stethoscopes that I have used have been Littmann. Between those two stethoscopes, the tubing was not as flexible in comparison to the MDF I received today, and I recently lost the diaphragm cover to my classic III which cost $20 to replace if you want Littmann pieces. Unfortunately, to replace the hardened tubing on both of my Littmann stethoscopes would essentially be the same if I were to purchase two new stethoscopes. I was surprised when I learned that MDF was the next best quality stethoscope out there and on top of that, underrated and underused in my opinion. My stethoscope arrived today and I marveled in the flexibility of the tubing and the adjustable head piece to properly fit my round head when using it. The diaphragm is turntable so it can be used as an adult or pediatric device. To my surprise, the stethoscope came spare parts (replacement diaphragm covers, two different sizes of ear pieces to accommodate ears, and the bell adjustments for different patients) and silicone covers that can be sanitized between patients without damaging the diaphragm cover. I definitely did not get any of this, aside from extra ear pieces, for my Littmann. I listened to my Bfs lung sounds and they were as clear as day. His heart sounds were clearer than with my classic III, and even with the hygienic cover, the sound is unchanged. I will probably purchase a second one because the price is spot on with the value of this wonderful product. I’d like one to have just for inpatient care as well as my NP rotations. At some point, I’ll have one for home use and another for work.

Excellent
purchased for home use, appeared to be very similar to one used in medical office, works just as good and much cheaper than one bought thru medical supply store. good quality manufacturing so should last for quite some time.

Decent
Quality is about what I would expect for a stethoscope of this price. If this is all you can afford, then it is definitely decent--you can hear heart sounds, breath sounds, you have both bell and diaphragm, and the pediatric size is just right. There is too much noise from the dual tubing; I had a HP Sprague-Rappoport decades ago when I first started and I was hoping this would be similar. It's similar but nowhere near as good, but as I said, if this is all you can afford it works well. I can't speak to durability as I've only had it a short time.
