This remote control is really extra: used for a conference, it is very convenient to use, feels good in the hand, easy to use with a low probability of operator error. With Ubuntu 10.04 Lucid Lynx and OpenOffice 3.2, it worked on the first connection without any adjustment. In fact, she seems to emulate a few keys on a USB keyboard. Finally, the storage of the connector and a backup battery in addition to the supply battery is really convenient. Nothing to say, this is very good material at a very reasonable price.
