3M Littmann 4100WS Electronic Stethoscope, Black Review

I had bought an earlier model preceding w4100,the 4000 .It broke down two years into use requiring refurbishment and again it failed.When I spoke to productline[Tim] manager,he told me the failure rate is about 3 percent in 4000 and about 2 percent in 4100 and increases to above 3 percent in 3 years. When I told him about poor hardware reliability,he told me iphone does not last more than years,which is not a reply expected from him.He is defending the product high failure rate.The stethescope works well only when it works.For a premium product and for a biomedical product ,the hardware reliabilty and quality control is very poor.Annual life cycle cost of this product is 162.5 Dollars excluding batteries.I recommend people to buy at their own risk
