Fetal Dopplers.

Scarlett • Hello there. My name is Scarlett. I'm 24 years old, married, and expecting my first in March.
Where can I purchase one? I thought Amazon would have a decent selection, but they only sell one with poor reviews. I don't want to spend a lot of money, but I want a quality product. I couldn't find any fetal Dopplers for sale in stores except one.
