A gift from a friend, unused Original price $129 About this item: AWARD-WINNING SPLIT DESIGN: Unlike fixed ergonomic keyboards, the Freestyle2 allows you to rotate and separate the key modules up to 9" to achieve natural hand, wrist and forearm positions for your specific body type and preferences. ADJUSTABLE TENTING: The Kinesis KB830 model keyboard is pre-assembled with the popular V3 tenting accessory which enables 5, 10, or 15 degrees of tenting (without palm supports) to keep forearms neutral for an optimal typing posture. STANDARD MAC LAYOUT: The Freestyle2 for Mac features a standard Mac layout with Mac-specific hotkeys, shortcuts and multimedia keys to boost your productivity. No software or special drivers required. LOW-FORCE KEY SWITCHES: The Freestyle2 uses a custom membrane key switch that features a low-activation force and tactile feedback to reduce finger fatigue, impact and strain.
