Stethoscope works and looks amazing
First MDF stethoscope. Very nice material and strength. Does comfortably around my neck. Color is awesome. Works better than my other stethoscope. I can hear better and my hearing has diminished. Not heavy. Very versatile. The cost was so nice, low cost but very good stethoscope. Will buy MDF again.

Listen to your Heart-Talk.
You enjoy quality craftsmanship and materials, when you touch it and feel its weight. The appearance is striking. The audio is superb. It should last a lifetime. I’ve had atrial fibrillation for two decades. I want to listen to my heart on a regular basis for my own personal meditation. The results have been surprisingly therapeutic. It’s an extension of the notion of “Know Thyself.” I plan to leave instructions to gift it to a nurse, when I no longer have a use for it. It’s a beautiful work of art.

Great quality MDF
My son is an FDNY paramedic, and I bought him a littman and after he lost it 10 years ago I gifted him with and MDF, He loves the MDF so much more, and so this has been his 3rd and always have been MDF. Great quality, excellent durability, value for your money, accessories are included, and the over appearance is nice. MDF stethoscope is the way to go. A gift very much appreciated

Best purchase for me!
I'm not a pro at all. I'm a student. I was told to purchase another popular brand and was having difficulty with it. (Blood pressure) So I decided to try this one. It's made a huge difference. The tube is slightly longer. Which I like. It's less expensive. I can hear the korotkoff sounds alot better. Slightly heavier than my other one. I cannot judge true quality yet since I'm new to using one, but it feels like it will hold up very well. I purchased the all black one and I love it. The black really shines right now. I know that MDF is the company I will be purchasing from and I will recommend for anyone in my program.

Decent for general use.
This is a good all-around General use use stethoscope. It’s definitely not a Litman but it gets the job done for most tasks. I bought this one mainly just to keep in the house as a backup. It works perfectly fine for taking blood pressure or listening to lung sounds. It comes with several different squishy earbuds, which is nice as I have small ear canals so you do get options. The ear tips are easy to pop on and off and to replace as needed. The diaphragm and the bell all seem to be well-made and also comes with several replacement parts for that as well. The tubing is just the right length and overall the build quality is quite nice. Now it doesn’t have the same quality as my cardiology three which I use for work but for just generally having a back up and just one at the house for us to use for the family, this works great. I wouldn’t say that would be great in an EMS setting simply because The noise reduction is not as good as some of the higher end models and I can definitely still hear a good bit of road noise or other sounds from the environment. if you just need a good basic every day stethoscope for general tasks such as blood pressures or lung sounds or bowel sounds this will work great This will perform better than anything you purchase at Walmart and it definitely has better sound quality than a Sprague style or those cheapie little ones they market as nurse scopes here on Amazon. You don’t need to break the bank to get a decent quality Stethoscope. I would definitely recommend this.

Ottimo fonendoscopio
Ho acquistato questo fonendo dopo 4 anni di Littman Classic, che era andato incontro a severa usura fino a danneggiamento del tubo. Consiglio vivamente questo MD One, intanto ha un prezzo più contenuto del Littman, l'acustica è comunque ottima, il colore mi piace molto di più (nero e dorato) e ha garanzia a vita e gommine di ricambio incluse. Anche il tubo è leggermente più lungo e flessibile. La testina è dotata di protezione in gomma ed è girabile (campana o piatto). Super consigliato!!!

Calidad a un precio asequible
Buena calidad de auscultación. Adquirido para sustituir a un Littman y apenas he notado diferencia. Viene con recambio de membrana y olivas de tres tamaños. El sonido es perfecto probado en distintas situaciones para uso veterinario.

NO LO RECOMIENDO
No me gustó , no se escucha como un litteman. Además ni me devuelven el dinero porque ni me contestan.
