Das Keyboard 4 Professional

Pros

• +Cherry MX Brown or Blue at purchase — the established professional switch choice with 20 years of manufacturing reliability
• +Anodized aluminum top panel eliminates flex and vibration under sustained heavy typing
• +USB-A passthrough reduces dock cable count — practical under a full programmer workstation load
• +Zero software required — no driver install, no configuration app, no firmware management overhead
• +N-key rollover handles any realistic simultaneous key combination during coding sessions

Cons

• −Full-size only — the numpad occupies permanent desk real estate whether or not you use it
• −Wired only — no Bluetooth or multi-device switching
• −No QMK/VIA and no hot-swap — switch and layout you buy is what you type on for the life of the board
• −Cherry MX Brown feels dated next to modern gasket-mounted or lubed tactile switches at comparable price tiers
