Special products to each customer

[Moesborg]

My wish is that a customer (after login) ONLY see the products that are intended for him.

I expected that it should be dealt with "Shoppers", "Shopper Groups" and the individual Product (or Product Category).

But I can not get it to work. Is there one here who knows the procedure?

Thanks in advance
