The idea for the Kensington USB flash drive in the presenter turns off battery power, is the only very good idea. The receiver LED indicator makes the USB flash drive diagnosis mend something.
Unfortunately, however, lacks the "F5" -Play button to start the presentation that I do not want to miss at Logitech.
The well-known from the computer keyboard repeat function is missing when you press the button longer. If you want to browse from a distance from the computer fast is almost lost in Kensington.
When removing from the computer of Kensington has little earlier problems with the radio connection. The Logitech Presenter has slightly more reserves.
As the laser beam of the two devices is the same.
