OPTICAL TRACKING TECHNOLOGY - The ELECOM "EX-G PRO" wireless trackball mouse 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. 3 DEVICE CONNECTION - Mouse can be connected 3 different ways (Bluetooth, wireless USB, or wired USB) to accommodate a wide variety of devices from PC, laptop, mobile phone, tablets, and more. Easily switch between the connection types with a single button. In wired connection, there is no need to worry about battery life as power is being drawn from the connected device. CUSTOMIZABLE 8 BUTTONS - Comes with 8 physical buttons and a tilting scrollwheel for an additional 2 buttons. In total, 10 buttons can be customized using the Mouse Assistant software for quick and convenient navigation. ADJUSTABLE DPI RESOLUTION - Designed with a high-performance optics system sensor and lens. The DPI button can be changed or set based on personal preference. Default settings are changeable between 500 (LOW), 1000 (MID) and 1500 (HIGH) DPI, making the movements of your cursor faster or slower. EASY MAINTENANCE - The large ball rolls on three small ruby ball bearings, allowing the rolling action to be smooth during use. The large ball prevents dust and dirt from getting trapped in small bearings, so less frequent cleaning is needed. To remove the ball for cleaning, push the ball out from the ball-remover-hole.
