Absolutely delivers what it promises

I, too, was skeptical when buying,
is there written repeatedly of a crossover if you want to hang a multi-switch for other receivers on a Quad LNB (for 4 receivers without multi-switch).
Simply screw all 4 cable from your LNB on the 4 inputs of the new multi-switch and you can expand any.
Has everything worked out great.
Thank evaluating a buyer I am also afraid to buy and therefore I would like to write again about my positive experience.
