The RC-GZ1 is a universal remote control engineered for compatibility with nearly all Roku devices and Roku TVs, including Streaming Stick+, Roku Ultra, Premiere, Streambar, and televisions from TCL, ONN, Hisense, and Sharp. It features voice control for content search, channel launching, and menu navigation, along with standard controls for volume, input switching, and app access. Setup is straightforward—install batteries, press the pairing button, and power your Roku device for automatic recognition. 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 unit.
