Utter garbage. Avoid this waste of money.
I bought two of these "simple easy-to-use" items, in the hope of extending our SkyHD & Sky multiroom to our kitchen and son's room. What a waste of money. Neither works or even picks up a signal from the coaxial cable (which has been checked). The instructions do NOT provide for SkyHD, despite what they say. The process is completely different from normal Sky or Sky+.
It's not simple. It's not easy. It just does not work. A total waste of money and considerable time and effort (going under our house to run and drill holes for the coaxial cable).
Avoid, avoid, avoid.
