The RC-GZ1 is a universal remote control engineered as a direct substitute for Roku RC-151 models, 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 controls manage volume, input switching, and app access. Setup requires battery installation followed by pressing the pairing button while powering your Roku device for automatic recognition. The RC-GZ1 replaces RC-FA5, RC-AL5, RC-AL2, RC-FA1, and RC-81 models, though app shortcut button configurations may vary by unit.
