For a few days, our Roku 3 remote ceased working for stretches of time. Rather than replace the controller, or even replace the Roku device, we got a Roku TV.
The space where we have had our TV is a bookcase with a cabinet designed for the old box variety of televisions which existed back in 2003. Rather than destroy the cabinet, we got an expandable wall mount. Spent a bit of time doing measurements and such to get the mount perfect, only for the power to go out in the neighborhood a couple hours.
