I regularly have to present at project meetings and service management briefings.
Working for Fujitsu we are normally supplied with a Fujitsu branded 'VersaPoint Communicator Remote'
The Versapoint whilst a very capable unit has the problem that it is all too easy to click the button mapped to escape. Even if you are well practiced with the device - every now and then you will find yourself dropping out of the presentation part way through.
I bought the Kensington solely to avoid this problem and have sincecome to love it. It provides four simple functions:
* Next Slide
* Previous Slide
* Laser Pointer
* Fade to black
Pure simplicity - it can be operated without looking with no chance of pressing the wrong button.
Unlike some other remotes, the USB radio dongle plugs into the device and whilst in the remote disables all functions effectively powering off the device to prevent battery loss.
To use just pull out the dongle (the pointy part at the bottom) out of the device and plug into the presenting computer. Wait for the green link light and your off.
When the dongle is plugged into the computer the remote sits so comfortably in the hand. It is small enough to be reasonably hidden from view if required - yet the buttons are big enough and well laid out so not to miss.
Runs off a standard calculator button battery (CR2032 i think) and lasts a long time.
Such a good device I unplug the provided remote when I speak as a guest and use mine.
