I must admit I was sceptical about ordering this product for my partner - we are expecting our first baby and she is very nervous about everything and worries a lot about the baby.
The reason I was sceptical was that not knowing if the baby has a heartbeat is one thing, but trying to hear it and not getting anything, for whatever reason, will cause her (and me) to become more stressed than we were before - potentially risking the pregnancy over nothing.
My mind was soon at ease when the product arrived and, within a couple of minutes, we could hear the unmistakable 150bpm of the baby's heart. Believe me, you know it's not the mother's heart or her dinner being digested, there is no doubt at all!
Every time we have used this product we have found the heartbeat within 60 seconds, usually 15-20 seconds. She is now 15 weeks pregnant, and I'd probably say that we got this around the right time, as the baby is definitely moving upwards now and every day it becomes easier. We also know that baby is wriggling about, as the heartbeat moves/becomes louder/softer without moving the probe.
Watch a few videos on Youtube about how to find the heartbeat and then use this product, you won't be disappointed. As I said, I was sceptical, but now I am happy that we got the product as it really helps the mother relax and is really easy to use.
