This Deluxe Prenatal Heart Listening System is a fantastic piece of equipment to have while you are expecting your baby. With this system, you can hear your unborn babies heartbeat, hiccups and kicks. This system includes two headsets for mum and loved one and cables to record precious sounds to your home stereo. To use this all you have to do is position the belt that holds the sensor in place against your skin and follow the instructions included on CD. I wish this was around two years ago as I would have defiantly had one to be able to hear my baby and put my mind at ease that every thing was ok with the baby.
