This is not a nurses stethoscope. If you need to listen for lung sounds, heart arrhythmia's or bowel sounds this is not the right tool. If you're looking for something to take simple blood pressures it's perfect for that. Its cute light weight and you'll hardly notice it around your neck. It's a great beginners stethoscope for CNAs or even as a toy for kids who aspire to grow up and work in medicine. When it comes to medical equipment you often get what you pay for. Don't expect it to behave like a Littmann.
