Keyboard very good but with a very big flaw. In closed position during transportation keyboard screen a large horizontal bar brand. My screen was not damaged because there was a transparent protection. This defect is due to the vertical positioning of the tablet system (groove) that touches the screen in the closed position and the lack of height of the rubber feet at the corners of the keyboard supposed to keep a space between the same keyboard and monitor. A mandatory to use screen protector. Second fault the Caps Lock key does not work therefore mandatory maintenance manual. No dedicated software logitech
