---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- 💡 [Designed to Reduce Wrist and Arm Strain] Since there's no need to move the mouse, the design minimizes strain on your wrists and arms. Using a mouse for long periods of time can cause wrist and shoulder pain. If that's your problem, we highly recommend a trackball mouse, which reduces fatigue and saves space. The EWIN trackball allows you to control the cursor by rolling the ball with your thumb. Its ergonomic shape fits comfortably in your hand, ensuring comfortable operation. This is the perfect solution for those who experience strain on their wrists and shoulders. For efficient and comfortable work while reducing strain, try an EWIN trackball. 🌟 [Various Button Functions] This comfortable and easy-to-use trackball mouse features left and right buttons, a wheel, and a DPI button that lets you adjust the cursor speed to suit your needs. This DPI button allows you to adjust the cursor speed to five levels: 200 counts, 400 counts, 800 counts, 1200 counts, and 1600 counts. This makes it easy to perform everything from detailed tasks like Excel and drawing to larger screen tasks. It also features forward and back buttons (not compatible with Mac) for convenient web browsing. 🔗【Convenient Wireless Connection】The energy-efficient Bluetooth chip and advanced 2.4GHz micro-receiver technology provide a connection range of up to 10m. It ensures a stable connection even in crowded wireless environments. It supports both Bluetooth and USB receivers, so you can use it with devices without a USB port. 🔋【Up to 18 Months of Battery Life】Power-saving technology allows for up to 18 months of comfortable use with just one AA battery, without the need for battery changes.
