Filco's Ninja has the same layout as a standard US keyboard, but instead of having legends on the top of the keys it has legends on the front of the keys. This Keyboard combines the high quality typing feel of Cherry MX switches, steel mounted in a rock solid body with full N-key Rollover function, all put together in a very slick package. N-Key Rollover allows multiple simultaneous key presses to be recognized by your computer. A big help for the superfast typist or serious gamer. These keyboards just make you want to type. The Ninja comes with 2 sets of Windows keys 1 set top printed, 1 set front printed, and a key puller to help you change the keys. Tactile feel, ergonomic click action (Brown switch). Gold contacts. 4.0mm travel. 2.0mm actuation point. 55g ~ 2oz actuating force keyswitch. Switches tested to 50 million actuations. Blue LED's.
