from the instant i plug in the usb receiver to the moment i throw the keyboard into a closet in a rage , this combo have give I nothing but trouble . while the mouse work just fine -lrb- although it be too small for I -rrb- , the keyboard should be recycle immediately off the assembly line . it be repeatedly launch iTunes and skip letter . for example , i can not type a capital r use the left shift key . i contact logitech support , but they could not or would not do anything to fix the problem . all driver be up to date and setpoint refuse to be of use . if you buy it , i hope you be one of the lucky one .
