Those who prioritize comfortable operation / those who do desk work for long hours / those interested in ergonomic design / those who want a simple to use mouse without setup / those who are on their second trackball mouse / gadget enthusiasts…🌈🌈🌈 🌈What makes the ProtoArc EM05 NL unique?🌈 The body is tilted at 62°, allowing for a natural wrist angle and reducing strain on the wrist. It's a vertical thumb-type trackball that helps reduce arm fatigue because it can be operated without moving the mouse itself. Being wireless, it can be on uneven surfaces such as your lap, or in your preferred posture, significantly reducing wrist movement and making your forearm much more comfortable. The 34mm ball is large, providing high operability, and it's a vertical trackball with an ergonomic design that conforms to the structure of the hand and arm. 🌈🌈🌈Connects to 3 Devices🌈🌈🌈This vertical trackball comes with one USB receiver and two Bluetooth ports, allowing you to connect to three devices simultaneously using multipoint functionality. You can quickly switch between devices using the button on the back. When using multiple devices or monitors simultaneously, simply press the switch button to switch between them. The switch button flashes a number, making it easy to see the connection status. This Bluetooth mouse offers high connection stability and can be with Windows, Android, Mac OS PCs, and other systems. 🌈🌈🌈Rechargeable and Eco-Friendly🌈🌈🌈 This wireless trackball mouse is eco-friendly and environmentally conscious, as it uses a rechargeable Type-C-USB battery, eliminating the need for traditional batteries. Equipped with a durable 500mAh high-capacity battery, it can be fully charged in approximately 2-3.5 hours using the included charging cable, providing approximately 120 hours of continuous use and 200-250 days of standby time. With fewer charging cycles and no need to frequently replace batteries, it's kind to both your wallet and the environment. It also features an energy-saving mode, allowing it to enter sleep mode when not in use. 🌈🌈🌈5-Stage DPI Adjustment🌈🌈🌈 The ProtoArc trackball mouse offers easy switching between DPI settings (200→400→800→1200→1600), high precision, and user-friendliness. It also features numerous buttons for versatile operation. Compared to a regular mouse, the ball provides smoother control, significantly improving efficiency, especially for dual-monitor setups. [Please note that this trackball mouse is not suitable for extremely delicate tasks such as gaming or drawing.] 🌈🌈🌈Space-saving🌈🌈🌈 Not only is the ball movement smoother, but you don't need to move the trackball mouse itself on your desk, so it takes up significantly less space. Being wireless, it's also highly portable. Unlike wired mice, you can use your computer at your desk, on the sofa, or even while relaxing in bed or under a heated table when it's cold, and you don't even need a mousepad. [Points about size] Because it is a vertical trackball mouse, the EM05 trackball mouse is suitable for medium to small hands. If you have large hands, the space for your little finger may be narrow, and you may not be to it, so please be aware of this beforehand. 🌈🌈🌈Technical Conformity Mark Acquired & 1-Year Warranty🌈🌈🌈 Because it has obtained Japanese TELEC certification (Technical Conformity Mark), communication is stable and you can use it with peace of mind. Furthermore, ProtoArc products come with a 1-year manufacturer's warranty from the date of order. If you experience any problems or damage, please feel free to contact us by email.
