Optical Switches for Light Clicks: The X2 V2 introduces pre-sorted optical switches, ensuring every click is light and ultra-responsive. Experience swift actions with minimal effort. Since optical switches do not rely on physical contact, they do not suffer from the same wear and tear and bouncing issues that can cause double-clicking in mechanical switches. New Pulsar Encoder for Tactile Control: Built with a tactile and dust-proof structure, it offers a responsive feel and longevity. Exhausted by the challenges stemming from third-party components, Pulsar has taken control and engineered their own fresh encoder - The Pulsar Blue Encoder. 4K Polling Dongle Included: Elevate your gaming with 4K polling via the included Pulsar 4K dongle. Unlock ultra-responsive inputs for a heightened competitive advantage. Improved Battery Life and Reading with Nordic MCU: The Nordic MCU enhances battery life and reading accuracy, ensuring extended gaming sessions without compromise.
