I do many presentations. The Targus AMP02US Notebook Wireless Presenter has dual controls for mouse or presentation mode. The built in laser works fine. Buttons are simple and in presentation mode and it is difficult to hit the wrong button. In mouse mode you can navigate more easlily than with the remote mouse controller for my projector. I often use other projectors or video sources and the Targus AMP02US Notebook Wireless Presenter allows me to always have remote usage. I have already recommended this model and Overstock to others.
