The RC-GZ1 is a universal remote control engineered as a replacement 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. Setup is straightforward—install batteries, press the pairing button, and power your Roku device for automatic recognition. The RC-GZ1 replaces models RC-FA5, RC-AL5, RC-AL2, RC-FA1, and RC-81, though app shortcut button configurations may vary by unit.
