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.

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!

Just as good as the others
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

I bought one for nursing school. Before I got the MDF, I was using a Littman lightweight. However, I feel more comfortable with my MDF b/c a) lifetime warranty b) It's a lot longer in length than my Littman c) it is also a lot louder. d) cheaper in price.

This stethoscope is amazing!
I went to a nursing supply store here in Las Vegas convinced I was going to pay $150 or more for a Littman. The guy behind the counter was very nice and let me listen to the various Littman models using my son as a guinea pig, and I must admit I was quite impressed by the Classic II and the Cardiology III. I was quite amazed when the clerk told me that I would be wasting my money if I did not at least try the MDF stethoscope. From the moment I removed the stethoscope from the box, I could tell this was a quality product as the tubing seemed thicker. When I tried the stethoscope on the ear pieces seemed nice and soft and fit snugly enough to drown out most of the surrounding noise, and the clarity when listening to my son's heart beat and breath sounds was as good if not better than any of the Littman products I had just tried. Then the clerk told me that free replacement parts were included for life. I was expecting to pay $100 or more for this product, so when I was told the total would be $55 with taxes, I wasted no time in purchasing this stethoscope. As long as this brand is around, I will never pay $150 for a stethoscope again. Thanks for making a great and affordable product MDF!

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.

Received the stethoscope on time, here's what I felt about it. Pros: - SOUND QUALITY AS GOOD AS LITMANN CLASSIC 2 SE - RICH LOOK, ATTRACTIVE DESIGN - COMFORTABLE TO WEAR. Cons: - Bit heavier than most stethoscopes available in the market. - Tubing is bit rigid. Now, I want to compare it with SOUND QUALITIES (BOTH CLARITY AND LOUDNESS) of some of the stethoscopes commonly used in INDIA. MDF 777 MD ONE : 8.5/10 LITTMANN CLASSIC 2 OR 3 : 8/10 MICROTONE CLASSIC : 6.5/10 DIAMOND ST 012 : 6.5/10 Dr MOREPEN ST 02 : 7/10 Most awesome part about this steth is its lifetime warranty! 😀 More details to be added once I use this for more than 6 months ☺

装着してみた感じといい、患部にあてた感じといい この777は、全てが想像以上の出来でした。 肝心の音響部(チューブも太めでいいです)もステンレス製で重さも音質もほぼ文句ないレベルです。 このお値段でこのクオリティーは凄いの一言。 747XPがアルミ製の安価タイプですが、ユニセフの御用達製品というのも頷けます。 替えのダイヤフラムや耳の形状に合わせて二種類(装着済みも入れれば三種類)のイヤーチップ付属はありがたいです。 細かい点ですが、ベルと膜の切り替えが今どこに合わせているのかも判るように「・」の印字がいいです。
