I received a Littmann Classic II Pediatric Stethoscope for medical school graduation 6 years ago. It served me well through Pediatric Residency, and then two years into private practice. Recently, probably due to my constant use and the resultant abuse my stethoscope receives, the tubing cracked. So, I replaced it with this brand new Littmann Classic II Pediatric Stethoscope. I bought the Caribbean Blue with the Rainbow Head. My only issue is that I don't particularly like the gold/brass finish of the metal parts. The rainbow finish is fun, but I will have to adjust to the gold finish of the rest of the metal parts. Most importantly, I can hear very well through this stethoscope. A pediatric cardiologist I worked with during residency was even very impressed with the sound quality of this stethoscope.
