ELECOM Trackball Mouse/Forefinger/8 Buttons/Wired/Wireless/Bluetooth/Black

DEFT PRO is a high-spec model wireless trackball that uses long-life parts and has a 3-year warranty. This index finger operation type has a wide range of finger movement and allows comfortable cursor operation. The left and right buttons use 10 million-times durable switches manufactured by OMRON, which is highly reliable in terms of durability and has a good reputation for its click feel. The wheel scroll uses an optical encoder that does not wear out parts during operation and has excellent durability. By using long-life parts, we offer a 3-year warranty. A wired connection cable and a wireless receiver are included, and you can choose from three connection methods depending on your usage environment: wired, wireless, and Bluetooth(R). Batteries are not required when using a wired connection using the included cable. Bluetooth(R) connection supports Bluetooth(R) 4.0. We have adopted a high-performance gaming-grade optical sensor as the sensor that detects the movement of the trackball, and have thoroughly analyzed the trackball color, coating layer thickness, etc. that are suitable for the optical sensor to achieve the ultimate pointer tracking performance. A large artificial ruby with a diameter of 2.5 mm is used as the support ball. By using only the highest quality support balls with smooth surfaces, the feel of the ball is greatly improved.
