The Kensington Presenter expert green laser with cursor control is in general a good product. However, the new cursor function is positioned in the centre of the control surface, which is a bad place. I will explain - when you are operating the forward/reverse buttons it is very easy to accidentally press the cursor button as well, which will move your presentation to the next slide. That is a nightmare scenario for a presentation - thus I rate this item with only one star.
I liked the previous model, as it was simple to operate. The cursor function could be nice, but it is wrongly implemented in this presenter. Besides the presenter works well.
I will try to return the item and get the normal model, without cursor function, which is surprisingly more expensive (you wonder why)
