Dual sensors for ultra-precision.

Good: 4G dual sensors are very precise; Comfortable and steady hold; Looks gorgeous; Adjustable side buttons
Bad: Drivers load up all 7 profiles whenever any changes are made
Price: AED 310

Now let’s talk about the dual 4G sensor system. This new technology is actually a combination of existing tools to get the job done with even more precision. Basically the 4G system combines a laser and an optical sensor to get the job done. The job, in this case, is an insanely high 6400dpi and surface detection that, according to Razer, is “10 times faster than any sensor” before.  What this meant for me, not as a professional gamer, but surely a connoisseur of gaming mice, is that movements across the board were very precise. In all the time while playing TF2, MW2, L4D2 and WoW over the past 2 weeks, I didn’t have one instance where the mouse skipped a beat and I missed my mark.

In part this was also due to the fact that I made some minor adjustments within the drivers to suit my taste, namely changing the polling rate and tracking distance (under ‘Surface Calibration’), to ensure the Imperator performed exactly how I wanted it to.

If there was one thing that I didn’t like about using the Imperator was that every time I accessed the drivers, it had to “read” all 7 profiles before loading the full driver. And every change also meant saving it to all the profiles on Synapse Onboard memory of the Imperator. It just made dealing with the tweaking of the Imperator a cumbersome experience. So no fault of the mouse actually, it’s just poorly optimized drivers. Surely there has to be some way for the profiles to be taken into account without all seven being accessed all the time.

So the new Imperator’s 4G dual sensors do a bang up job of keeping the mouse precise by reading the surface in the most optimal way possible. The DPI count maybe a little too high, but I’m sure people with 30” monitors working in Photoshop will appreciate the extra precision. It looks great and feels confident under the palm of your hands. It’s surely not as flashy as some of its higher-end siblings, but it gets the job done in the most smartest and efficient way possible.

From auditing to editing, I now test and analyze the latest gadgets and games instead of the latest financial statements. Both jobs are equally intense and rewarding. When I'm not burning up hardware in the name of science, you'll find me nuking in DOTA 2 or engineering in TF2.
