Gigabyte Aorus K9 Optical Mechanical Keyboard Review

Rating: 7.5.

In this review we take a look at the Gigabyte Aorus K9 keyboard which utilises optical mechanical switches from Flaretech – designed to be faster, more durable and splash proof. The switches themselves can also be hot-swapped for a custom gaming experience. With other features including RGB backlighting, integrated cable management and a set of included PBT keycaps, it sounds like a pretty good deal for £110 – but is the Aorus K9 as good as it sounds?

KitGuru says: The Gigabyte Aorus K9 is a decent option if you want to try out optical mechanical switches but the software lets it down.
