I have one and hardly use it @cutieondutie28 if they are laying a funky way it can make it difficult to hear. I do have frequent appointments so maybe that's why. I originally wanted to get it because my husband's hasn't heard them since 7 weeks.
Definitely! I got mine from EBay for only 40 bucks !
I got an angel sounds one off of eBay for 17$. It's worked perfectly.
