✅《Optical Tracking Technology》The ELECOM trackball provides precise cursor movement for superior accuracy so you can get where you want on the screen quickly with less hand movement, improving productivity and efficiency.
✅《Functional 8 Buttons》It is very easy to move in any direction. It comes with 8 physical buttons on the device and the two extra buttons are the scrollwheel tilting that allow horizontal scroll.
✅《DPI Cursor》Designed with a high-performance gaming optics system sensor and lens. The DPI button can easily change between 500(LOW), 1000(MID) and 1500(HIGH) DPI, making the movements of your cursor faster or slower.
✅《Easy Maintenance 》The ball rolls on three 2.5 mm large artificial ruby ball bearings. They are extremely smooth and the relatively large size prevents dust and dirt from clogging them. So you don’t have to clean the ball bearings too often. The ball is held in place by the ball bearings, but can easily be popped out of the device, by pushing it through the hole in the bottom and it can be easily cleaned.
