The Logitech R400 is a wireless presenter designed to give you more freedom and control during your presentations. By connecting the included USB receiver to your computer, you can move naturally around the room within a 15-meter range, avoiding the need to stay tethered to your laptop. The device features a red Class 2 laser to highlight key points on your slides, and intuitive buttons allow you to navigate through pages, trigger the F5/ESC command, or blank the screen to redirect the audience's attention back to you. Weighing only 57 grams, this black presenter is lightweight and ergonomic, fitting comfortably in your hand for long sessions. It runs on two AAA alkaline batteries, providing up to 13 months of use for the remote controls and about 20 hours for the laser. The package comes with a carrying case to keep the presenter and its mini USB receiver safe, making it a practical tool for professionals using Windows 10 or 11 who want a simple plug-and-play setup.
