If you want roku tv IR remote look for the crescent moon key for sleep timer, only roku tv remotes have it. You can also get the $19.99 voice remote it won't work with your roku tv straight out of the box, it has to be paired. Unlike IR remote which just with when the batteries are put in.
The ones shown in box are wifi remotes that have to be paired first.
The roku remotes with the four channels keys right in row instead two by two, if it has power key and volume keys along the side its roku tv remote. Similar looking remotes without a power key won't work with roku tv's.
