The Kensington Wireless Presenter with Red Laser 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 & Play 2.4GHz of 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.
