Here's something new, Gigabyte introduces its first gaming keyboard with optical mechanical switches. The AORUS K9 Optical features the contactless Flaretech switches from Adomax, these promise a much longer lifecycle as well as a much quicker debounce time than mechanical switches.
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.
