We adopt optimized silent scissor-foot mechanism for all our keyboards. It greatly reduces typing noise to avoid disturbing surrounding people, making it suitable for libraries, offices and public quiet spaces. Meanwhile, the structure brings soft, consistent keystroke feedback and long service life with durable rebound performance.
