I never liked this service; we got it back when my wife's soaps weren't available same-day online. The user interface is terrible, even as a software engineer I can understand how it's set up but not how they could imagine any human being, myself included, would like it.
But the worst of all is the way they cheat you. At installation time they make you buy some of the equipment but lease other parts (and they hide the detail that what you're only leasing includes a box attached to the dish on your roof, until you try to discontinue), and they send an installer. But when you want to quit, they require return all the "leased" parts, and they don't even promise that you'll be charged less if you send back the main receiver without the box from your roof.
Absolutely no reason to give these jerks any of your money.
