Had me this Presenter acquired by the increasing presentations in the Technician Abendschule me something easier and more professional figures. The timer function is great if you're tied to a predetermined time. It is programmed into the device before it and after it vibrates inaudible to the listener, but clearly for the presenter. Wireless connection is also great and the USB receiver for the PC is super stowed in the Presenter itself. But can indeed would be a smaller Unify receiver okay.
