Kensington Pro Fit Ergo Wireless Keyboard

Pros

• +Split and sloped key layout separates the hands toward a more natural shoulder-width posture
• +Built-in cushioned wrist rest cradles the wrists — no separate pad to buy or align
• +Adjustable reverse tilt slopes the board away from you to keep wrists flat
• +Dual wireless — 2.4 GHz nano receiver and Bluetooth — so you have a fallback if one path drops
• +Full-size layout with numpad; quiet, spill-proof keys and a 3-year limited warranty

Cons

• −Membrane switches, not mechanical — quiet and office-appropriate but no tactile bump
• −Single-piece board — the halves don't physically separate like a true two-piece split
• −No backlight or per-key programmability
• −Runs on replaceable AAA batteries rather than a built-in rechargeable cell
