(This comment is struck on this keyboard I use non stop since early October 2014) I use this keyboard with my laptop ASUS A95V, although it is wide enough for the keyboard of this laptop of 18.4 "is not willing and I admit I struggle with the chiclet keyboard. I do 3 to 4 hours of entry with this Microsoft keyboard and mouse, though very basic, offers great comfort of use. Moreover, I chose this wired together just for a fairly intense use, wireless sets for I remain confined to the occasional multimedia use or media center in the living room. There at least, no need to change the batteries every 3 days and the cable length allows for a willing workstation thus increasing my comfort.
