Although I was extremely dissatisfied with my purchase the seller made it right. He buys different parts of satellites from different vendors and puts them together to make one complete system. That's alright but not what I thought I was buying. The system I bought had parts that weren't new and didn't fit together properly. Therefore it caused many problems. The professional installer had to manipulate the parts to make it fit together. When it was finished it didn't look good but more important it didn't receive a good signal. But after contacting the seller he apologized for his mistake and was readily willing to rectify the situation. He replaced it with a new more expensive satellite system that he bought in a complete set. He also sent me a return shipping label. He went over and above to satisfy. I put up the new satellite system and it works great.
