Fetal Doppler??

Who has one that actually works and they like? In my first pregnancy we ordered a FaceLake fetal Doppler and it never worked right. They were going to make me pay as much as the thing costed to ship it back and get a replacement and there was no guarantee that one would work either. I can barely get my own heart beat to show up!

I’d love to get another one this time around because my toddler loves hearing the baby (and who am I kidding so do me and my husband). Anyone have a suggestion that doesn’t cost $300
