Smaller keyboard, so more room for the mouse. The 80% smaller size has responsive 60g Outemu Blue switches that give your keyboard a reassuring click. These switches provide a loud and tangible click when you press a key, which gives a very satisfying feeling when that happens with your perfect move. LIGHTS ON: You have full control over the lighting with six zones, seven brightness levels and the choice of eight mode presets. DON'T MISS A SINGLE KEYSTROKE: At tense moments, a missed test can mean 'game over'. With full N-key rollover (and a 50 million keystroke lifespan) you can hold down as many keys simultaneously for as long as necessary.
