Replaced a steel series world of war craft gaming mouse fits palm grip well this mouse exceeded my expectations by a lot great feel amazing look and nice mouse pad to go with it all

Great design and shape compared to my previous razr mouse i cannot complain the only thing i dont like is the software it wont update any settings until you reboot the machine still i was unable to control the light settings correctly i tested it on windows 7 pro and windows 8 pro same thing in both os
