I’ve had my Sprague X stethoscope for several years now. I recently needed a replacement tubing and the customer service department sent me everything I needed to fix my stethoscope promptly and at no cost. I feel like I have a new stethoscope at no cost to me. I’ve had a couple of other sprague rappaport stethoscopes over the years. This is by far the best stethoscope I’ve ever owned. No distortion of the sounds because of the tubes rubbing together. The price is great and also the quality. In my opinion, it outperforms much more expensive stethoscopes. I recommend this for anyone who wants a great stethoscope at a reasonable price.
