The Presenter Logitech is a real find for my seminars for me. Finally a laser pointer, I do not lose so quickly (my previous were so little things that were basically laid by me) and not the laptop stick more, while I go through the presentation. So I can before my subscribers are free, what more open and thus look more professional - before I had the feeling as if the laptop cover me and the effect of "spoiling".
Must install one nothing, just the USB part, which can be very conveniently stored in the remote control plug in, start Presentation and away you go.
As a buyer already wrote in his review in front of me - the most difficult was probably to free the little marvel out of the package.
