Part of me thinks multiple ones of them are actually fake. I saw more than one where the person described themselves as the "tech savvy" or computer person in their household / family, but "the Hopper was complicated even to me" or similar.
I also have to wonder why someone who did NOT buy their equipment through Amazon would go to Amazon to post a review. It's like they went out of their way to post negatively. That said, of the (6) 5-star reviews, as I recall, only (1) of them purchased their Hopper through Amazon....
