[M] Cooler Master CM Storm Trigger Z Gaming Keyboard Review
 

Trigger-Z represents a slight update from the original Trigger, comes with three switch options with different colored backlights and a large wrist rest for additional comfort. Thanks to the ARM core 32-bit CPU at 72MHz, we are able to work with the hardware macro playback function and five macro keys are available on the left side which can be pre-programmed thanks to the included software interface.
