Install and use correctly then rate it! – iStethoscope Pro Review

My husband installed correctly, we used the microphone. I have and IPhone 4S. It works good, we can hear each others heart beats. I downloaded it to try and hear my daughter in my belly, but I have not been able to hear her heart beat. Regardless it still works, just need to set it up correctly for those that say it don't work. Lol waste of $.99 cents for y'all, but it works for me!
