So happy to have my 9 old littmann look as good as new ✨✨ The rim kind of tore off 2 weeks ago, was sceptical about ordering here since it has a no returns policy .. even went to the lengths of checking on official littmann site to purchase a replacement, only to find out that Amazon’s the official seller. The original diaphragm of my stethoscope was perfectly fine so didn’t replace it with the new one. The delivery was prompt and the product definitely deserves a 5 star .
