While at first, the Littman price tag may scare away many, this stethoscope is definately worth the hefty purchase price. In my five years experience as an ICU nurse, I have owned four different stethoscopes. I wish I had just bought the Littman the first time and sticked with it! I was able to get my Littman at a slight discount by ordering through the purchasing department at my job (hospital). The clarity of sounds for auscultation on this model beats the ther Littman models and Ultrascopes I have used in the past. This model has held up well to a variety of messes and cleans up easily - ask me about the time when a bag of blood exploded all over me and a patient in ICU! This stethoscope offers a tunable diaphragm - so it can be used for both high and low frequency sounds as well as adult or pediatric patients - great for those days when I get "pulled" to ER to work! As an ICU nurse, I know how important it is to be able to recognize subtle changes in patients' heart or lung sounds, and this stethoscope is the one I always always have confidence in to provide me with the sounds I need to hear! Check it out - you'll be glad you did!
