Rainy 75 CNC Aluminum Mechanical Keyboard - Triple-Mode Violet

In this review the Rainy 75 is positioned as a compact, premium 75% mechanical keyboard for users who care about sound and build quality; the single biggest reason to buy is its noticeably refined acoustic profile thanks to custom lubricated switches and multilayer damping. The reviewer found the keyboard best suited to touch typists and enthusiasts who prefer a heavy, well-machined board with versatile connectivity, and notes the experience centers on the combination of a CNC 6063 aluminum case, pleasant switch feel, and a glass-steel aesthetic that elevates typical desktop setups.

Key Features

• Custom Lubricated HMX & JWK Switches: The factory-lubed Violet switches offer a smooth, consistent feel and a damped, raindrop-like sound that many customers praised for musicality.
• Sturdy 6063 Aluminum Alloy Build: The CNC aluminum case gives the keyboard notable heft and a solid, premium impression that reduces flex and improves acoustic resonance.
• Triple-Mode Connectivity: Wired, 2.4G and Bluetooth 5.0 modes let users switch between low-latency desktop gaming and wireless convenience for laptops or tablets.
• Advanced Sound Dampening: Five-layer foam and 14 dampening buds plus FR4 plates with flex cuts produce a pleasant, controlled sound signature and reduce unwanted vibration.
• Durable Keycaps and Aesthetics: Double shot PBT keycaps and RGB/PP/gradient glass-steel styling deliver long-lasting legends and attractive lighting for desktop setups.

Who It's For

This keyboard is ideal for mechanical keyboard enthusiasts, streamers, and gamers looking for a compact 75% layout with a premium metal case and refined acoustics. It also fits users who move between a desktop and a laptop or monitor, since the triple-mode connectivity covers wired workstations, responsive 2.4G gaming, and Bluetooth mobile use.

Less suitable are users who need a full-size layout with a number pad or those who want ultra-lightweight, travel-first keyboards; the heavy CNC aluminum chassis and substantial weight make it better for a stationary setup rather than frequent transport.
