Uea, lots of then have worked very well. However the fact remains if there ever is a problem with them Winegard has no clue how to properly trouble shoot or repair them. Their idea if testing one is by a signal generator. They never connect them to power, ask them to lock onto the proper birds and then verify they actually can see the correct sats. Just plane sad to me. It took me nearly three months of constant working with them, including over two weeks by a dealer service department, finally upper managment getting involved to get what should have been a relatively simple troubleshooting and repair job resolved. Winegard finally stepped up to the plate and did what was right,so yea, I was frustrated at the time. But now just feel their service department has to be some of the worst.
