The Labtec Wireless Presenter is a pleasing device that is comfortable to hold and provides all the essential functions. After a short test I immediately used it for a longer presentation. Here, the Presenter proved however to be extremely unreliable: After pressing the forward button, the presentation turned suddenly frantic to multiple slides forward, a controlled jump backward was also no longer possible, but any number of films was backward skipped. Despite Presenter I was ordered to "gearshift" go back in order to bring the presentation at all to the end can. Extremely unpleasant to large audiences.
Systematic investigation has since shown that this effect is * always * eventually enters, also in a controlled, radio-free environment and a short distance (1m) - course intermittent and not precisely reproducible, but so regularly that I disregard of further use of the device. I will therefore grow me another presenter.
