Razer Imperator 4G Review


Dual sensors for ultra-precision.

4G dual sensors are very precise; Comfortable and steady hold; Looks gorgeous; Adjustable side buttons

Drivers load up all 7 profiles whenever any changes are made

I tested the Imperator on my 3 year old, but still gorgeous Destructor mouse pad, whose surface color looked identical to the Imperator. The ‘ultraslick’ feet at the bottom literally glided on the Destructor’s surface and not once did I feel any...

Razer Imperator 4G 2012 review


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...

The Imperator 4G is expensive at £74. However, it is meant to be a gaming mouse and it does its job. If you are looking for a cheaper option also take a look at the Abyssus.

Razer's new and refurbished Imperator 4G 2012 boasts of dual sensors (optical and laser) and is a better product.

Razer Imperator 2012 Expert Dual Sensor Gaming Mouse Review


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...

In fact, I am still very impressed, the performance of this mouse is stunning and it is brilliant in nearly every gaming scenario I could possibly think to test it in. On top of that it does work well as a standard everyday mouse, and does look good...

Great Mouse


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...

RAZER Black 1 x Wheel USB Optical/Laser 6400 dpi Imperator 2012 Expert Ergonomic Gaming Mouse


It seems to work, at least for the first day

Impossible to register at - it is said that product with that serial number was already registered. So ; 1. I cannot register myself to get information about drivers updates ; 2. It is possible that I got a used...

Fantastic Mouse


I read some reviews where this was said to be "cheap" and "flimsy". I have beat it half to death, and there are no ill affects. I think they changed how the wrapped wire is attached, as I don't foresee a fraying problem. Last thing, there are two sets...

I read a few reviews regarding this mouse, and I will address what was "wrong" with it ; 1. Adjustable side buttons. Mine adjust and stick in place. They don't move a millimeter forward or sideways. I moved to this from a Logitech MX518, so I want my...

I am not going to call this a flaw of the mouse, but I had to put a piece of tape where the thumb goes as it was a bit slippery for me. It is beautiful, but not functional for me, hence the friction tape. This isn't a "flaw" in the mouse, just my...
