Amazon to the rescue!
So after 2 years of bouncing around an ambulance, my stethoscope broke. To be specific I punctured the diaphragm (long story, don't ask). Seriously not good since I also use it for my hospital clinical as a student nurse. I ordered the spare parts kit hoping it would make it in time. Amazon to the rescue! It made it, I'm good to go for my next clinical date. I should give 5 stars for that alone! But I'm actually giving it 5 stars because, well, because it's a good product. Price was right (actually I was surprised how low the price was considering it was Littmann). The kit came with a diaphragm and a set of ear tips. Both in black. I will admit it would have been nice to have a choice of colors, especially since the ones that came with my stethoscope were grey, not black (and the black does look kind of funny and out of place, but that's probably because I'm used to the black). First the diaphragm. It is tunable which is awesome! Also it was a one piece diaphragm/rim setup while the OEM that i was replacing was actually a two piece (one diaphragm and one rim, separate). It was easy to install, taking all of maybe 3 minutes to remove the old and place the new. Only problem was now it looked all weird with grey ear tips and a black diaphragm and rim. So of course I have to replace the ear tips so it'll match! The hole for the tips to slide over the tube was kinda small. Makes for a tight fit, sure, but seriously, it took me longer to install the ear tips than it did the diaphragm! But installed them I did, successfully I might add. I now have a working Littmann again and couldn't be happier (okay, well, I'd be happier if they had a grey option but still I'm pretty happy). Did a test run on my nephew to ensure everything worked well, and I'm good to go!

Great Replacement
Great replacement for my stethoscope. The fit, size and appearance all are perfect. Even if you bought them because the manufactured are not comfortable these are worth it. They are compatible with the Littmans as described.

perfect
It fits perfectly. Sooooo easy to install. I was going to send my scope to 3m to refurbish. ($150.) Nope. Less than $16. at time of purchase.

Good but wish you could just buy 1 of the parts
I bought this just for the plastic ring part to replace on my stethoscope and although the whole product was wonderful quality I wish I could have bought just the 1 part I needed. Overall though it is just as high quality as the parts that come standard on the Littman stethoscopes and over all I was happy with my purchase!

Eccellente
Qualità eccellente del prodotto originale, che non costringe alla sostituzione dopo diversi anni di utilizzo delle parti più sottoposte a usura. Buono il prezzo, ottima la velocità di consegna e la spedizione nel suo complesso.

Good fit.
Bought to replace diaphragm for Littman Classic III as original part had become loose after some time. Good press fit, same great sound quality. Ear pieces easy to fit. Looks brand new again - and considering you'd pay 70+ for a Littman III this is not the most expensive given its going to last and last after using and using.

Hej Jag har fått en fel vara på min beställning. Jag tror att jag har fått varan nr 40001. Jag bifogar bilder. Jag skulle vilja få en rätt vara och kan returnera den som är fäll. Jag förväntar mig att inte betala porto för att det känns inte att jag har gjort något fel. Mvh Andrzej Szlesinski
