A gaming keyboard from the well-known manufacturer A4 Tech, which boasts an extended set of features, as well as a reliable metal base. First of all, you should pay attention to the use of advanced Light Strike mechanical switches, which provide the highest response speed of 0.2 milliseconds, which guarantees a quick response of the game character to the player's instructions.

First of all, it is very useful for fans of shooters, but also useful in all games where you need a quick reaction and lightning speed of decisions. The A4 Tech Bloody B820R keyboard has a classic layout and a dedicated numeric keypad. There is a fairly bright RGB backlight with a choice of operating modes (there are 6 flicker modes in total). This model has a very high key threshold — from a distance of 3 mm. This is a whopping 25% faster than conventional metal switches. Long-Lasting technology creates an interesting typing sound effect that lasts even after months of heavy use. The device comes with 8 interchangeable keys.
