not all there kit is good. there higher priced mice and headsets are good gaming perifs. but there mice do have a tendency to stop reading the middle mouse click... that 1 in particular is similar performance wise to the new lachesis and naga both suffer the middle mouse problem.
there headsets i found to be pretty fragile. but the starcraft 1s look very robust unlike the Carcharias and orcas. sound wise they will be hard to fault.
