in any case, dont bother buying razer stuff, overpriced, overhyped, mouse has double click issues, keyboard usually last 1 year plus before some keys will fail
steelseries mouse moi using their rival 95 (pc bang version of rival 100) for daily use (not bad, sensor is ok, no double click issues but i dun like the clicky sound and feel when clicking), if play game then take out the zowie mouse
EDIT2: dont ever buy the logitech marathon mouse, ** 1, the sensor is off centered, and super inaccurate, wasted my $29
