Very pleased

Received just as pictured and it came with ultrasound gel. I was able to find the heartbeat after trying for about 10min. Definitely pleased with this purchase and would recommend it!

Great product

The Doppler worked great, we had no troubles finding the baby’s heartbeat! The reoccurring payment they put on my account for a one time purchase was NOT cool.

Works great

Used it and I was able to find the heartbeat. I couldn’t get a steady number but I was just happy to hear it!

Love it!

It gives me peace of mind being able to hear my baby’s heart beat in between appointments! Could be a bit louder but works awesome for the most part! Quick shipping and quality product!

Lauren Brim
Great product!!

Just make sure you have AA batteries ready so you don't have to wait to hear your baby's heartbeat!
