RA Bock Single Head Cardiology Stethoscope with Pressure Sensitive Diaphragm

** At least half of the negative reviews on this stethoscope were done by the Vorfruende Stethoscope company. They finally messed with 3M Littman and found themselves in a lawsuit and removed from Amazon. Trust me when I tell you that you are missing out on a real value in a stethoscope all because of the devilry of Vorfruende.** Single Head Cardiology Stethoscope: Real World Review by myself an ER Physician with 25 years experience: This is an excellent stethoscope choice if you are in the market for a large heavy Single Head Cardiology model like the Littman Master Cardiology model. Looks, size, and weight are virtually identical with the Master Cardiology model. The function is very good in my opinion as someone who has been using stethoscopes the past 25 years. We have improved this model with each production. Ear Tips are now a soft silicone and no longer screw on but push over the binaural exactly like Littman and will not unscrew or fall off. The single diaphragm is tune-able and responds with a simple pressure change to capture low and high-frequency sounds. Our mission is to provide less expensive medical diagnostics that have excellent function and to stand behind the products we sell. We also include a Lifetime warranty that covers the binaural, tubing and stainless steel stethoscope head. We include 2 sets of spare Cherry Soft ear tips and spare diaphragm and retaining ring with each stethoscope. **Comparison Pictures are meant to only show a comparison of our model and the Littman Master Cardiology it is NOT an offer to purchase both stethoscopes ** You will be very happy with the function of this stethoscope especially at this price with a Lifetime Warranty included.
