The rc-41 is the 3500 stick wifi remote, it will pair with newer roku sticks and other models of roku that accept wifi remotes, but isn't very useful without tv controls. The RC-ALIR is an IR remote, which work with roku express, premiere, and ultra's. No sticks. Again isn't useful without tv controls. Unless your rc-alir has tv controls then its a Roku tv iR remote and only works on roku tv's, no stand alone rokus like the ones listed above.
