The DX900 is a wireless gaming mouse with customisable button functions and an ergonomic design for both right- and left-handed users. The rear shell of the housing can be removed and replaced with a longer version if more support surface is needed for the hand. The 16,000 DPI sensor and the fast 1 ms response time ensure that mouse movements are transmitted quickly and precisely. The wireless connection to the PC is established via the 2.4 GHz USB dongle.
