The Verbatim Silent Mouse and Keyboard. Using new Silent Technology, silent click switches, and rubber covers, these Verbatim products are truly silent. The nano receiver is small enough to plug in and leave connected and the 2.4GHz wireless performance allows for a lag-free connection. The Silent Mouse features Blue LED technology, allowing users to point and click on more surfaces than other mice-from a glass table to the granite kitchen counter! The Silent Keyboard features a full numeric keypad and full-size function keys.
