Rectangular, practical, good\n\nThe ACK-540U+ is a mini keyboard with integrated Smart-Touchpad. It has a modern design in noble, matt black SoftSkin coating and appealing blue status LEDs for Caps, Num, and Scroll Lock with new Light-stripe design. It also has the full functionality of a full-size layout keyboard and an extremely silent key stroke and tactile feedback due to the high-quality X-Type membrane technology.\n\nWired\n\nThis SoftSkin keyboard is connected via USB 2.0 cable to the desktop or notebook computer.\nThe connection via cable is consistently estimated, since it is known for its reliability.\n\nCompact\n\nThey keyboard saves place because a numpad is integrated on the letters keys and can be activated via a function key. It also has an integrated smart touchpad with two mouse buttons for left and right click, thereby an external mouse also is made irrelevant.\n\nSoftSkin\n\nBy the rounded design and the SoftSkin surface, working and writing is much more pleasant than on a keyboard with a normal surface. The particulary quiet keystroke by X-type membrane technology is aboon for the ears.
