There's something about the curve of the Imperator that makes us think of the Protoss Reaver from StarCraft. Those Protoss must know what they're doing, though, as the Imperator is quite a comfortable mouse — assuming you're a right hander.
Each gaming mouse seems to have a gimmick to make it stand out from the other, and the Imperator is no different, this time with a sliding mechanism under the mouse that allows you to adjust the position of the thumb buttons back or forward. It does actually help, although we're surprised that only Microsoft has jumped on the much easier to use vertical button set-up.
There's another button under the Imperator as well, somewhat clumsily allowing you to switch between profiles. We had thought the whole "under mouse" schtick was a thing of the past, but then, apparently the past is in.
Things are otherwise quite predictable, with the usual buttons in place, as well as another two under the scroll wheel that by default adjust sensitivity. Of course, being Razer, every button can be assigned to something else, although in the wake of current Roccat and SteelSeries competition, the Imperator feels under apportioned in this department. Save your settings once done, and the Imperator stores them on the mouse itself, thanks to its on-board "Synapse" memory.
