Why choose the CORSAIR K100 RGB Optical gaming keyboard?

Great sensitivity

The Corsair K100 has OPX optical-mechanical switches that are great for typing and gaming. However, you must note that the switches are quite sensitive with a 1 mm actuation point and a 45g actuation force that bottoms out at 3.2mm. You’ll find yourself watching your actions while gaming for the fast few days. However, you’ll get used to the keys as you keep using the keyboard and have a better gaming experience each day.

Great processing technology

Corsair’s hyper-processing technology does all the grunt work, ensuring that your keyboard is up and running efficiently. The new engine supports a 4000Hz-polling rate, which is more than it needs and is often toned down to 1000Hz.

The iCue control wheel

The iCue control wheel has received mixed reactions. However, we have to say that it is an excellent addition to the keyboard since it makes it easier for you to control the RGB display.
You could use the iCue control wheel to dim your keyboard’s RGB lights by turning it left or right. You could also press the central button and turn the switch to skip between modes. The ring’s color is used to indicate the current profile on your Corsair keyboard.

Over 200 custom profiles

The Corsair has full RGB backlighting, individually lit keys, and 44 RGB zones covering the board’s right, left, and top edges. It has an 8MB storage that can store over 200 custom profiles that you could customize with the Corsair iCue software.
