Bests & Worsts Reviews from Amazon

Bought two for Christmas for the kids. They work perfectly well. The sound is quite clear for the cost of the stethoscope. We are physicians, and our $180 stethoscopes work better, sure, but not necessarily 30x better. My husband was impressed at the quality of the sound for such a cheap item. The stethoscope has a "dual head", meaning that you can choose which of the heads you place on the chest to auscultate. There's a side with a wide diaphragm, and a side with a smaller diameter "bell". You can turn the head to which side you want to use, and you'll only hear sounds if you place that side against your chest. If you don't hear anything, try placing the other side on the chest, or turning the head until it clicks! I think this is the reason why some reviewers are saying that they can't hear anything.
