Title: Barely even picks up mother's heartbeat!!!
Review: Expected it to be something like Doctor's doppler. It is just a weak sound amplifier with no filtering. It picks up external sounds like the hum of the refrigerator and the dryer very well. You just touch the outside of the unit and the sound is amplified louder than anything else. Mother's heartbeat is faint and muffled. Did not hear a single heartbeat or any kind of Baby sound. It did not even pick up visible baby kicks. Don't waste your money.
