Left-hand wired gaming mouse

The Jansicotek gaming mouse is a wired optical model built for left-handed users who favour a palm grip. It connects through a USB 2.0 port and offers twelve programmable buttons for macros or shortcuts. Adjustable DPI steps of 1000, 1500, 2000 and 4000 let you match sensitivity to the task, while a polling rate range of 125 to 1000 Hz keeps response consistent. The design targets both gamers and office workers who need extra side controls.

Ergonomic build with adjustable weight

A contoured body and smooth TEFLON feet pads aim to reduce friction during long sessions. Eight internal weights can be added or removed so the balance feels right for your hand. A six-foot braided-fibre cable with a gold-plated USB connector resists tangling and maintains signal integrity. The scroll ring provides standard vertical navigation without extra horizontal tilt functions.

Twelve programmable side buttons and lighting

The left side carries twelve number keys that can be remapped to any function through the companion software, giving quick thumb access to skills or commands. A dedicated fire button on the right delivers a triple-click with one press for rapid actions. Rainbow backlighting cycles through seven colour modes for visual feedback. Driver support covers Windows XP through Windows 10 and Mac OS X 10.4.
