Start by matching range, receiver type, and essential controls. Look for a model with a reliable USB receiver and a 2.4 GHz connection, common across brands like Logitech and UGREEN, offering about 10–15 meters of real-world range. Check compatibility with your host devices (PC or laptop) and your presentation software. Consider the number of buttons and features you need, such as slide navigation, laser pointer, or a hyperlink button, to keep control simple on stage. Finally, pay attention to the battery indicator and expected battery life so you won’t be caught mid-presentation.
