About 2 1/2 hours and it was his first Hopper install. But he knew what he was doing and there were no problems encountered. He did have to replace the 59 with 6 to the room the Hopper is in. That probably took 10 - 15 minutes of the 2 1/2 hours. And he spent time explaining what he was doing as he did it. Twice because my son lives upstairs where one of the Joeys went. Now I have to connect my EHD and be patient while it does it's thing like a 922 and everything is fully functional.
