I currently work in a moderately busy ER and having the ability to Bluetooth the breath sounds and heart sounds to either my phone or wireless headphones has been a game changer. I no longer have to bring my full stethoscope into rooms that are suspected of having COVID-19 or any other airborne or contact precaution rooms. This allows for less contact with my equipment and for a faster and easier decontamination of everything. This was well worth the money. When I had an issue with a connector not being right when I first got my EkoCore Digital attachment, Roanne in customer service immediately fixed it and sent me a replacement at no charge. Thanks for developing such an awesome product.
