Remote Red Laser Presenter puts you in control of your presentation and your audience. Conveniently portable and easy-to-use, it allows you to focus on what matters most - your presentation. Simple forward and back controls are complemented with a clever blackout screen button letting you hide your slides while you manage them or direct attention away from the screen and to you. Plug-and-play, 2.4GHz wireless technology means you don't need to worry about interference from other devices or unnecessary cables. Bright red laser beam makes illuminating your key points easy. With a rubber textured grip, the Presenter remote is ergonomically styled to fit comfortably in the palm of your hand. It is compatible with Windows 7, 8, Vista, XP, Mac OS and Lion OS.
