ERROR-CORRECTING DESIGN FOR ULTIMATE COMFORT

Unique adjustable hinge allows you to customize the trackball angle from 0 to 20 degrees according to your needs, ensuring a more natural and comfortable hand position for all-day use.

EASY AND PRECISE NAVIGATION

The ProtoArc trackball mouse offers accurate and smooth tracking, letting you navigate through documents and web pages easily. No need to move your arm. Just control the cursor with your thumb for a more comfortable and productive experience, especially in tight spaces like a messy desktop, couch, or bed.

WIRELESS AND POWERFUL

Plug and play. This trackball mouse supports triple connection modes—Bluetooth, 2.4G wireless, and wired. Easily control up to three devices simultaneously, switching between PC, laptop, and iPad with just one button. Compatible with Windows, Android, Mac OS, and more.

BATTERYPERSISTENT AND ADJUSTABLE DPI

Built-in rechargeable lithium battery. No need to change batteries. Remember to turn it off when not in use to save power. 5 DPI settings (200/400/800/1200/1600) let you adjust cursor sensitivity easily for smooth tracking.

QUIET AND FOCUSED

Smooth frosted surface and quiet clicks enhance the user experience. No need to worry about bothering others. Focus better while working.

CARE AND MAINTENANCE

After using the trackball for a while, clean it and the three rollers inside the hole to maintain smooth operation. The middle scroll wheel may not be completely silent, and buttons and back/forward buttons may not be compatible with Mac OS.
