---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Laser tracking, adjustable resolution up to 1600 DPI.

The X-keys L-Trac trackball features a large, high-density trackball housed inside a high-impact ABS molded enclosure. This enclosure is ergonomically designed to fit the contours of your hand, eliminating side-to-side arm and wrist movement. The trackball accommodates both left- and right-handed users and all hand sizes. The easy-to-use trackball is suitable for people with disabilities and physical impairments. The faster you turn the trackball, the faster the cursor moves across the screen. The large, high-density trackball, combined with a stainless steel roller, provides a "silky smooth" feel and easy control.
