Very good product !! 2467

This reassures many moms hear their child.
But we must have a good hearing and dexterity to successfully capture beats (and not those of the mother).
A tip for all requires that the mother is still lying quietly for at least 10 minutes, if the child moves too much and it's super hard to find his little heart.

There are for me only 1 problem (no big deal), I wanted to pick up the sound on my pc but the jacks for headphones picks up interference, the sound soon become disgusting. So it's a good product just to listen.

However, I still want to recommend this product which is a good compromise quality / price.
