I’ve been using a base model stethoscope for years and have known for a while that I needed an upgrade. I have sensitivity to noises around me and have so much trouble with auscultation if anything is off (owners talking, pet moving, too much fur etc). I have used this stethoscope for one day and I’m sold. Never going back! I think it would be a disservice to my patients to have anything less, and that isn’t hyperbole. The sound quality is amazing, the ability to deafen the noises around me is great, and owners LOVE to hear their pet’s heart through the app. I even found a new murmur. It’s amazing and I am really grateful to have this at my disposal. Told 3 vet friends about it at the end of my first shift using it - it’s that good! If you’re on the fence, get it! You won’t be disappointed.
