Honestly, you may be better off buying accurate Roku accessories from a local retail store. I’ve bought an RCAL7 Voice Remote from a local Walmart store about almost two weeks ago, for my Roku Express+ 3910.
I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
