equipment functioning apart from the mouse wheel which "slips" into space (I have several wireless mouse, hp, and the logitech microsoft 3000v2 no problem). It is a set range start, the keyboard is slightly hazy (although he does not rest on these 4 pads), plastic is low-level, same keys for a touchdown which means (however silent if we forget the noise the entire keyboard due to her veil), no key lock indicator for caps or keypad. Satisfied with my purchase without for this set, I was looking into buying a price to equip an old desktop that this material did with the disadvantages mentioned before (I expected better by buying microsoft).
