I have been looking for an electronic/ amplifying stethoscope for a very long time. This one delivers on so many levels. I have some moderate hearing loss and have always had problems auscultating heart and lung sounds. I feel that I am back to confidently being able to differentiate sounds. Add in the ability to go wireless into a COVID room or the ability to use a visual display and I'm sure to feel safe. Thank you all for making this product... I cannot see why anyone would use a conventional stethoscope . I would like to see the addition of dust covers for the charge port and for the acoustics chamber when going wireless. You can find dust covers for less than 30 cents each. Thank you!
