The RRST01 is an infrared remote designed as a direct substitute for the Roku RC-ALIR EXPRESS (model 3026000025), compatible with Roku streaming players and televisions from TCL, Hisense, ONN, Sharp, Philips, RCA, Westinghouse, and similar brands. It provides Power, Volume, Mute, Sleep, and dedicated streaming shortcut buttons with large mechanical keys, front-facing volume controls, and a secure screw-in battery cover with tassel. The remote includes a learning function to program commands from an original TV or audio remote for extended control options. As an IR-only device, it requires direct line-of-sight operation and does not support Roku Streaming Sticks, voice control, or private listening features.
