Tesoro Excalibur is a mechanical keyboard with an advanced backlighting processor. Unlike the original Excalibur which is capable of recording and storing macros, Spectrum also has a number of stunning illumination modes. Using this keyboard is a lot of colorful fun. Excalibur is the first Tesoro keyboard to have a classic solid look. It can be used with a gaming rig as well as on an office desk due to its straight and strong lines. The supreme spectrum backlighting, however, adds more color to our guy. Each key"s color can be set individually, the illumination will react to keystrokes, change colors in different ways, and do other crazy things.
