Here we have a new wireless mouse from Spire, the DXT. Adopting a vertical ergonomic design (avoid extreme twisting of the forearm helping to improve your comfort when using the mouse), this compact mouse makes use of a 2.4GHz radio frequency (works up to 30ft away from your computer) and comes with four DPI settings (dots per inch) 500, 1000, 1500 and 2000, and a micro-USB dongle.
Measuring W55mm x L44mm x H80mm and weighing 160 grams, the DXT is powered by a 250mAh lithium polymer battery that provides up to two weeks of continuous driving time on a single charge (120 minutes charging time). Pricing and release date are still unknown at the moment. [Product Page]
