Easy to put on and much more cost effective than buying a new stethoscope.
My first stethoscope was a gift from my sister when I was in nursing school. Unfortunately it had dried out after being cleaned so often during COVID and pieces started to get stiff and break. Since I could not afford to buy a whole new stethoscope I decided to try and just replace the pieces that broke. This replacement snapped on super easily and has not popped off since. It handled being used a cleaned frequently and outlasted my stethoscope that finally got too stiff to use comfortably. I’ll definitely buy this again if I need to replace more parts!

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!

Amazon saved me with this order!
I love my Littmann stethoscope and was so devastated when I lost one of my diaphragms at work. I didn’t want to buy a whole new one, so I was so relieved that Amazon has a spare parts kit online. The order came right before my next shift and they work amazing. The appearance looks just like the original one, and they are high quality. I will definitely be ordering more if I need to.

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!

Buen producto. Original.
El repuesto es caro pero por rehabilitar tu estetoscopio vale la pena. Lo mejor es que ¡existe! y es bastante sencillo de recolocar. Se complica un poco la búsqueda por los diferentes modelos pero ayudan mucho las imágenes.
