The I-Rocks Laser mouse looks big & heavy, but do not be fooled. It is by far the lightest mouse I have ever used. Gamers looking for an ultra light part should definitely consider the IR-7330. Contrary to its light size, the pressure needed to use the buttons is higher than with other gaming mice. The build quality is quite good and the paint job is comparable to any of the big mice like the MX series or Microsoft mice. The scroll wheel looks great and should draw some attention during LAN parties.
