Product Description 

The A4Tech OP-620D is a staple in offices across Pakistan because it "just works." It combines a simple plug-and-play USB setup with advanced vertical light technology for unmatched accuracy.  

Key Features of the A4Tech OP-620D:

• Patent 2x-Button: Say goodbye to the double-click. Just one press on the 2x button opens files and folders instantly. No drivers are needed, making it a true efficiency booster.  

• Precise 1000 DPI Tracking: The high-definition optical sensor ensures the cursor moves exactly where you want it. It is designed to track on difficult surfaces, including furry textiles and wood.  

• 4-Way Wheel Scrolling: The smart scroll wheel supports both horizontal and vertical scrolling, which is a lifesaver when navigating large Excel spreadsheets or wide web pages.  

• Dust-Resistant Design: The scroll wheel is sealed to prevent dust accumulation, which is the #1 cause of wheel failure, significantly prolonging the life-span of the device.  

• Ambidextrous Ergonomics: The symmetric shape fits comfortably in both the left and right hand, providing a natural grip that prevents cramping during long hours of use.  

• Extreme Durability: With buttons guaranteed for 5 million clicks, this mouse is designed to withstand years of daily heavy use in home or office environments.
