However, I also want to mention the issue of the disadvantages of the product. The forward and back button act and compose herself cheap to (slight wobbling and audible click when pressed). The Presenter are relatively thick, however, is still well in hand. The problem of the thickness is that they can not be stowed as pleasant and Flashy act. However, most serious criticism is the location of the USB receiver. To achieve this you must remove the battery cover and then reapply, in itself not a big expense, but for frequent users a KO criterion.
Why now won 4 stars?
The price-performance ratio of the Presenter is really impressive. When we see as a "loaner" for faculty and students their commitment and for this we do not really need a to the often expensive Logitech Presenter.
