Ashamed of Revain for letting the vendor claim they "repair" these devices. Unless the previous owner called Comcast and turned it off while logged into their account, the modem cannot be used by anyone else. Mine arrived yesterday and Comcast found it. a west coast user can use it. After playing around with Comcast's modem tools for an hour, my tech found a little-used tool called "Xcaliber" that I used to remove the old registry. The tech said there was almost no documentation for it in Xfinity, and a friend just told him it existed. So an hour later I had a working SB8200. It will take some time to find out how well this works. Might be worth 5 stars. But for now this seller and product get 1 star due to false advertising. It has not been renovated. Happiness when washed off with soap and water! And I see hundreds of reviews on Revain and eBay all talking about useless cable modems that can't be released from their previous owner's account. dr Ted Cooper retired Revain
