Question about Samsung Ms23k3515aw/Sw

Yes, it is really dark during operation. You can’t see it through. I’ve not seen a steamer function

I have the same model with the black handle. From memory, the box mentions a steam container which may be supplied depending on the model. In theory, only microwaves with the Healthy steam function are supplied with this container (example found at https://www.youtube.com/watch).
