Negative Positive
Title: Good tool.
Review: This product specifically says in the directions that you may not always be able to hear the heartbeat (depending on the baby's position). My husband and I appreciated this product because we were able to speak to the baby through the speakers and play music. If you have that desire than this is a great product to buy! As far as what you hear...you'll hear his movements, and may occasionally hear his heart beating, but don't buy it just for that, you will be disappointed if you plan to listen to the beating consistantly.
