Know before you buy
The 4K dongle allows the mouse to communicate with your PC at a 4,000Hz polling rate. This provides significantly higher responsiveness and smoother cursor tracking, which is particularly noticeable on high-refresh-rate gaming monitors.
While the mouse is rated for up to 80 hours of battery life, this estimate is based on a standard 1,000Hz polling rate. Using the 4,000Hz mode will increase data transmission frequency and result in faster battery depletion.
The Lamzu Thorn features an ergonomic shape specifically designed for right-handed users. It is generally best suited for claw and palm grip styles, though its lightweight 52g frame makes it comfortable for various hand sizes.
Despite having a solid, hole-less shell, the mouse remains impressively lightweight at just 52 grams. The solid design actually improves structural integrity and provides a more consistent, premium feel in the hand compared to honeycomb-style mice.
Optical switches use light beams to register clicks rather than physical metal contacts. This eliminates the risk of double-clicking issues over time and provides near-instantaneous actuation with zero debounce delay.
Yes, you will need to use the Lamzu software to toggle the polling rate settings and ensure the mouse is properly paired with the 4K dongle. Once configured, the settings are stored on the mouse's onboard memory.
