ARRIS SBG7400AC2-RB DOCSIS 3.0 (Open Box)

I have Xfinity as my provider who first recommended I blow 200 bucks on an Arris G36. Lost 160 bucks on that as by the time I installed it, too late to return. Then they recommended an Arris T25. Still have that dust collector as same deal, can't return and no one will give me 20 bucks for it. Finally called Arris who knew their stuff and they recommended this WIFI model that I purchased for 65 bucks refurbished and works great. Arris customer service dudes seem to be from India but work in downtown Philadelphia. Don't care as the folks at Xfinity are nice, don't give me a hard time when I want to purchase a piece of equipment of my own but I lost around 400 bucks until I finally called Arris and knew exactly the model I needed. Long term, I'd save 15 bucks a month. It appears I’m not the only person out there whose provider doesn't have a clue. Moral of the story is to call Arris, tell them your provider and what devices you need and they will save you hundreds of bucks unless you try to install it right away and can return it. Anyone out there want an Arris T25 in mint condition? JK as I'll post it again on Facebook's Marketplace for 15 bucks and see what happens.
