The RC-GZ1 is a universal remote control engineered as a direct substitute for the RC-EL2, offering seamless compatibility with Roku Streaming Stick, Roku Ultra, Premiere, Streambar, and Roku TVs from TCL, ONN, Hisense, Sharp, and other manufacturers. Voice control functionality enables hands-free content search, channel launching, and menu navigation, while standard buttons provide intuitive control of volume, input switching, and app selection. Setup requires simple battery installation and pairing via the dedicated pairing button—no additional configuration needed. The RC-GZ1 replaces legacy models RC-FA5, RC-AL5, RC-AL2, RC-FA1, and RC-81, though app shortcut button configurations may vary by device.
