So overall happy with the purchase :) Has some pros: the backlighting of the keys through the letters, which means the characters will not be erased on the keys! to a narrowing milestone, which almost eliminates an error with pressing an adjacent key, or pressing two at the same time! Got cons: there is no stand for the left hand; the sound of the keys is too loud (and this despite the fact that it has an optical contact !). Each time you turn on the computer, the keyboard backlight setting is lost!
