The Kensington Wireless Presenter with Red Laser Pointer 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 & back controls are complemented with a clever blackout out screen button letting you hide your slides whilst 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. The bright red laser beam makes illuminating your key points easy. The presenter remote is ergonomically styled to fit comfortably in the palm of your hand. Powerful 2.4GHz connectivity allows up to 60 feet of operational range. Connect the Wireless Presenter by plugging the wireless 2.4GHz USB receiver into any standard USB port on your laptop or desktop.
