Top quality at a top price. This mirror is worth its price. He's really tough, it wobbles nothing when one has mounted a stable holder. Also the arm is very stable and no comparison to these armed mirrors, in which the arm is totally unstable. The reception at Astra goes to 99%, which I can not judge, obs is located on the mirror or at the maximum XO-Line 64, 6 degree monoblock Quad LNB. In any case, both work together tip.
