Great product
I found my baby’s heartbeat at 12 weeks most heart warming sound!

Buy it!!!
I was very skeptical of this product and website as there weren’t many reviews. I got my Doppler in 3 days. It worked perfectly and eased all of the anxiety that has been building. Took me maybe a minute max to find the Baby’s heartbeat the first time I used it. So happy I made the purchase.

Worth every pennny!!!
I got this for some peace of mind because I had lost my last pregnancy. I was skeptical about it even working. But not only did it deliver to my house the next day after worked perfectly! It felt so good to hear my baby's heartbeat. I am 17 weeks today, haven't felt any movement yet, which isn't abnormal but I was worried...this thing made me so happy.

Worked great!
I'm 12 weeks and picked up the heart beat after a few tries and a good you tube video that had some tips on how to pick it up early on. Once found it was very clear. The heart rate did not match the numbers displayed but I just wanted to hear it so that's no matter to me.

Great at home device
I have loved having this ant home to listen to my daughter. I miscarried my last pregnancy so I just wanted a little extra reassurance this time that baby was doing well before I felt her. I used it first at 14 weeks and it was extremely simple and easy to use and find a great sounding heartbeat. It’s user friendly, good quality and provides a great peace of mind when you just want to check in on your little one between early doctor visits.
