Bought a new dvr from their own website, no software available so I had to call their tech support. One hour to do setup then afterwards I noticed how loud the internal fans were, you could hear them from across the room. Now I have made four phone calls, sent them three videos and a picture of the serial number and this lady hung up on me. AT&T does the same thing, they harass their customers until the customer stops calling. Well, we'll just see about this.
