The Dual Optical Mouse from Logitech uses optical sensing technology for defining the pointer movement on the screen. It features a top-notch finish with a two-tone colour combination that gives it an elegant look. The design of the device is, however, biased in favour of a right-handed user. The device fits snugly within the palm and is comfortable to use, thanks to its shape. A rubberised side grip near the thumb pro-vides excellent lateral hold to grasp the mouse.The buttons are well laid and comfortable to use, with a well-balanced scroll wheel that provides a good tactile feel. A fourth button placed near the thumb is a good programmable stand-in. What sets the device apart from others is the use of two 800-dpi optical sen-sors for better accuracy and handling. The mouse showed good directional stability and accurate pin point precision in applications such as Photo-shop and gaming.
