Rainy75 Aluminum Mechanical Keyboard

The BFKK Rainy75 is a 75-per-cent layout mechanical keyboard built from 6063 aluminium alloy. It ships with custom-lubricated HMX and JWK switches and a cocoa switch option. Five layers of foam and 14 dampening buds combine with FR4 plates featuring flex cuts to create a refined acoustic signature. Triple-mode connectivity covers wired, Bluetooth and 2.4 GHz wireless operation.

Enthusiasts seeking premium acoustics

Typists and gamers who value a dense aluminium chassis, factory-lubricated switches and extensive sound-dampening will appreciate the Rainy75. The three connection modes suit both desk-bound and mobile setups. Buyers who need a full-size layout with dedicated number pad or a plastic-bodied budget board should consider other form factors.

7000 mAh battery capacity

The integrated 7000 mAh battery powers the keyboard during Bluetooth and 2.4 GHz use. Wired latency is listed at 2 ms, 2.4 GHz at 3 ms and Bluetooth at 7 ms. A silver SUS304 weight bar adds mass and stability. No other capacity or endurance figures are supplied.

Questions about this item

Will the 2.4 GHz wireless dongle work alongside my older USB 2.0 hub?

The 2.4 GHz wireless connection operates at 3 ms latency and plugs into any standard USB port, so it works with older hubs without extra drivers.

How can I confirm the five-layer foam and 14 dampening buds are actually reducing ping?

Tap a key and listen for a muted, consistent thock sound across the board — that acoustic signature shows the foam and buds are seated correctly.

Does the box include the FR4 plate and SUS304 plate, or do I buy one separately?

Both the FR4 plate with flex cuts and the silver SUS304 plate are included; no extra plate purchase is required.
