Mine was a fetal heartbeat monitor, u can hear your babys heart beat when ever u want and when it hickups or just moving around. It helped me to bond early with the baby and tape sounds from the womb that my partner could listen to and understand more what was going on in there. They retail at $99.95 but i brought mine off ebay for $52.00. Reccommend to anyone who is pregnant.
