I had it for 3 months and switched to TWC. The concept is there, but it's not ready yet, because AT&T puts too many restrictions on what you can do with your network. I loved the 4 room DVR, but not necessary for me. Like satellite, you have to have a box at every TV. Rental fees for boxes at four TVs, when I really only wanted digital cable at one, and basic cable at the other, non-HD TVs, was a lot more than I wanted to spend on extras that I didn't want/need. The cable boxes are run through the modem, but it doesn't add any cool features that you should get by having all of your devices interconnected, and if the modem locks up and needs reset...the whole sytem locks up and has to wait for the modem. The modem locked up at least twice a week. It was a lot more expensive than TWC digital cable, with a similar lineup. Also, similar to satellite prices. The internet speed was not what it was cracked up to be. Their standard speed is 6 Mbps (much slower than my TWC speed). If you want to go to 10 Mbps (still slower than my TWC speed), it costs quite a bit more, and 18 costs alot more.
Alot of people on here like(d) it. I had a bad experience with it, and the UPS store that I returned the equipment to, said that they were getting multiple equipment returns everyday. For as limited as their availability, I can't believe that that's a good thing to have that many returns.
