The optical technology enables a lifetime of up to 100 million keystrokes and the keyboard is fully waterproof, Gigabyte says you can even use it under water. You can choose between Red and Blue versions of the Flaretech switches. Other features include RGB LED lighting, swappable switches, and NKRO.
Not sure about the MSRP but I can see it listed online for 129EUR.
