Buffalo unveiled its latest line of stylish wireless mice for desktop PCs, with battery life of up to 18 months, under the SRMB04 series. Available in six 2-tone glossy color options, the SRMB04 are right-oriented 5-button scroll mice, with 1500 DPI optical sensors. The mice are loaded with aggressive power-management features that turn off the sensor in short intervals of activity, to conserve power. Measuring 73 x 110 x 41 mm (WxDxH), weighing about 74 g (without battery), the mice take in two AA-size batteries to run. These feature rubber-padded scrollwheel and side thumb-rest. Slated for late April, the SRMB04 mice are priced at 4,620 JPY (US $56.6).
