The RC-GZ1 is a universal remote control engineered as a direct substitute for Roku RC-GR3 and compatible with nearly all Roku devices and Roku TVs, including Streaming Stick+, Roku Ultra, Premiere, Streambar, and televisions from TCL, ONN, Hisense, and Sharp. Advanced voice control enables hands-free content search, channel launching, and menu navigation, while standard controls manage volume, input switching, and app access through simple tap or voice commands. Setup is plug-and-play: 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.
