PerfectStroke

From Yenra

The Logitech PerfectStroke key system, which provides a typing experience that's comfortable, fluid and silent. PerfectStroke is designed to create longer key travel - 3.2 mm compared to 2.2 mm - than that of typical notebook keyboards; as a result, the distance your fingers have to travel to activate a key is optimized for your comfort. Micro-scissors distribute force evenly across key surfaces - even if you strike the edge of a key, the key stroke still feels the same.
