A great little tool. I am using it to do exams of suspected COVID patients in their car. Cut up a backup stethoscope and attached the Eko. The combination ends up being 6" long which can be passed into their car. I can stand safely away and hear breath sounds and cardiac sounds. Using noise cancelling headphones. Easy to sanitize diaphragm. The Eko is sealed up in sandwich bag then disposed after each patient. My only issue is that it seems like the volume is a bit quiet in real time. When I record the sounds I can increase the volume a bit more. Not a huge issue though and I would highly recommend it as way to do exams without exposure.
