What it is

BFKK Rainy75 is a 75-per-cent mechanical gaming keyboard built from 6063 aluminium alloy. It ships with custom-lubricated HMX and JWK switches plus Cocoa switch options for a refined typing feel. Triple-mode connectivity covers wired USB, 2.4 GHz wireless and Bluetooth. An 7000 mAh battery powers the wireless modes.

Who it suits

Enthusiasts who want a premium metal chassis, deep acoustic tuning and the flexibility of three connection types will appreciate the five-layer foam, 14 dampening buds and FR4 plates with flex cuts. Buyers who need a compact 60-per-cent layout, a plastic chassis to save weight, or a keyboard without per-key RGB should look elsewhere.

Deciding specification

The 6063 aluminium case combined with five-layer internal damping and 14 silicone buds defines the sound signature and rigid typing platform that separates this board from lighter plastic alternatives.
