Beautiful Stethoscope!  The sound through the ear piece is very clear, clearer than my Littmann.  I am not currently sold on the ear piece plastic as it is a harder plastic (not hard, just harder, not as soft) than my previous stethoscope and I tend to have sensitive ears; I will have to see if the smaller ear pieces that came with it fit better.  The 'scope is weightier than my previous one, but not an uncomfortable weight; It feels substantial.  I have yet to wear it over a 12hr shift so I'm not sure if it will get uncomfortable as time goes by.  The name tag is a nice bonus to help keep your 'scope from growing legs and wandering off.  I am very happy with the lifetime parts program; I hope to not have to use it anytime soon, but to have the option without buying a new "scope is awesome!
