・【Ergonomic design to reduce wrist strain】 Ideal for those who easily experience fatigue in their wrists and arms during long work sessions. The approximately 15° natural tilt and shape that conforms to the hand maintain a natural posture and reduce strain on the wrists and arms. Because the cursor is operated with the thumb, there is no need to move the entire arm, making desk work more comfortable. ※Please check the size chart before purchasing. ・【Large ruby ball & high-precision sensor + PHILIPS advanced chip for smooth tracking】 Comfortable to use in limited spaces such as desks, sofas, and beds. The combination of a 34mm diameter large artificial ruby ball, a high-precision sensor, and a PHILIPS advanced chip achieves smooth and accurate tracking. It supports five-stage DPI adjustment of 800/1200/1600/2400/3200, allowing you to select the optimal precision according to the application. ・【Bluetooth/USB compatible, simultaneous connection to up to 3 devices, easy switching with one touch】 It is possible to connect to up to 3 devices such as PCs, tablets, and smartphones simultaneously. A dedicated button allows for one-touch switching, reducing stress when using multiple devices. Bluetooth saves USB ports, and stable connection with the included USB receiver is also supported. The bottom of the main unit is equipped with a receiver storage space for convenient portability. ・【Energy-saving performance with up to 18 months of use with a single battery】 The power-saving design allows a single included Philips AA battery to last up to 18 months. This reduces the hassle of frequent battery changes and leads to reduced running costs. It is a stamina performance that gives peace of mind to those who use it for long periods of time. ※Varies depending on usage environment. ・【90% silent clicks & 7-button configuration for improved work efficiency】 The silent design reduces click noise by approximately 90%, allowing you to use it without worrying about disturbing others in quiet environments such as late at night, in the office, or in the library. The 7-button configuration, including shortcuts such as "forward" and "back," improves browsing and work efficiency. It achieves a high level of both comfort and operability.
