Razer are one of those big companies that have been in the gaming peripheral market for quite a long stretch, so it's always with some excitement that we crack open a box of one of their latest products.

Looks great; Very comfortable; Incredibly sensitive DPI; Very accurate; Excellent software

Bit expensive for some; Macros are limited to certain number of keys

It is very intriguing to note that instead of releasing totally new products, gaming peripherals manufacturer Razer has implemented their new 4G dual sensor technology on its gaming mice and rebranded the famous Imperator and Mamba as Imperator 4G 2012 and Mamba 4G 2012.

KitGuru says: A great product from Razer that has everything we could possibly ask for.

Looks and feels great, works well, while it lasts. 2 stars because it broke down after less than 2 years of use. Just came out of warranty, too. Not recommended at all, at this price.

great product, arrived on time

It's pretty fast and accurate, but the only problem I have with this mouse is that I almost always have to be on a flat surface so if youre one of those people who do not have a mouse pad I recommend you buy one with it. Other than that this mouse is great it's beautiful and the grip is nice.

I have had this mouse for about four months now and i play games such as Battlefield 3, Planetside 2, Tribes ascend and pretty much every other good fps game. This mouse is perfect for all of these as it glides smoothly and has a very nice feel and click.

For day-to-day use you might not care too much about dpi G-force handling or polling rates. But if you're a hardcore gamer any little edge you can get over your opponents is worth it. The Razer goes all out to maximise your gaming skills with a 6400dpi 4G sensor.

Dual sensor nice feel high dpi

Right-handed no extra weights pricey

The Razer Imperator may not offer as many features as some other hardcore gaming mice, but it's one of the most comfortable models we've ever used, and it offers great performance.

Wireless version would be welcome; no left- or right-leaning clicks on the scroll wheel

Razer have tried to create one of the best mice possible with the Imperator 2012. They have incorporated two sensors in what they call the 4G Dual Sensor System which gives a very impressive 6,400 DPI and should allow it to track on any surface due to the combination of an Optical and Laser Sensor.
