【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. Three connection types to choose from: Bluetooth, 2.4GHz wireless connection, and wired connection. You can choose the connection type that best suits your needs. Rechargeable included: Simply connect via USB-C using the included cable to charge. The charge provides approximately 4 months of battery life. Precise control is achieved through the horizontal twisting motion of the ball: By twisting the ball horizontally, you can easily scroll through websites and Word documents. Symmetrical design for both right-handed and left-handed users: The low-profile design makes it suitable for both right-handed and left-handed users. It can be used for long periods of time while reducing strain on the hands and arms. Optical tracking technology enables precise and accurate cursor tracking and scrolling thanks to its dual sensors. It comes with a 3-year warranty. Regarding the friction noise when using the Slim Blade Trackball: The ball is supported by three pillars, and slight friction occurs during operation, so it is not "silent." Cleaning the ball with alcohol or cleaner may remove the surface oils, which may actually increase the friction noise. If dust or dirt accumulates on the pillars, wipe them with a soft cloth or cotton swab.
