Cool thing, it works, the diaphragm is sensitive. You can hear the heart beating, the child is delighted

Cool, came more bright, beautiful, everything is heard, especially a knock on the heart

Very good quality for your price. Ideal for children without having to resort to a toy.

Very nice and good quality, the worst the transport company that doesn't bring it home

I haven't set it up yet, so don't know how it's gonna go. But it looks great.
