The RC-GZ1 is a universal remote control engineered as a direct replacement for Roku streaming devices, including the 3500x stick model. It features voice control functionality for hands-free content search, channel launching, and menu navigation, along with standard controls for volume, input switching, and app access. The remote pairs automatically via plug-and-play setup and is compatible with Roku Streaming Stick+, Roku Ultra, Premiere, Streambar, and Roku TVs from TCL, ONN, Hisense, Sharp, and similar brands. It replaces RC-FA5, RC-AL5, RC-AL2, RC-FA1, and RC-81 models, though app shortcut button configurations may vary by device.
