The R.A.T. M by MadCatz uses a Laser sensor, providing a DPI/CPI range of 25 - 6400dpi (in 25dpi steps). This results in a tracking speed of 6 m/sec, and a maximum acceleration of 50G. It uses a USB Nano Dongle & Bluetooth (33ft / 10m range) connection.
Sleek, versatile, and decidedly next-gen, Mad Catz' R.A.T. M Wireless Mobile Gaming Mouse gives you the performance you would expect from a R.A.T. and combines it with the portability of a notebook mouse. Featuring the latest Bluetooth technology – as well as a nano dongle for devices lacking Bluetooth connectivity – the R.A.T. M is just as comfortable at home as it is in the office. With programmable action buttons and an intuitive drag-and-drop software interface for button customization, this is the premiere mouse for the gamer on-the-go.
