WE have WOW and the digital adapter was self service. I'm surprised we are still married!!!! My DH is the kind of guy, open package remove item and hook it into something! Even though A might fit into D, he will have it into C just because that was the first thing he saw. He couldn't thread the coaxels. So it is on, I don't like it, the stations change slowly and we haven't been able to program the remote that comes with it. It will change the channels but you turn the TV on and off with the TVs remote. But I want to change to Insight so that's OK!
