I have never really had an issue with Dish, other than the Hopper 1.  The tech who installed that one, was very polite and answered all of my questions.  With the Hopper 1, it would shut off on its own.  After many months of complaining to Dish, via the PM on Facebook, the same tech who hooked up my Hopper 1 was the same one who changed the wiring, and then he asked me if I wanted to upgrade to the Hopper 3, which I said a big Yes!!! After installing, the many questions came with quick answers. I did not have any issues with him being in my home.  I knew that was part of it, in order to get the upgrade.
