"I'll never go back." It's a phrase that pops up again and again in comments and customer reviews for the Razer Orbweaver , the follow up to the Razer Nostromo . Gaming keypads – specialised half-keyboards used by gamers – offer a level of comfort and control that even the best gaming keyboards fail...

Adjustable parts for optimal comfort; 20 programmable keys; Best thumb controls available

Pricey; Keys lack tactile differentiation

Let me start by saying this is my first "gaming" mouse. I've always used stock mice that came with my computers until I finally decided to buy this mouse from Razer. The first thing I noticed was the comfort. Using it for a long period of time didn't leave my hand feeling tired like some other mice.

One of my best buys yet

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

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.

Watch out for the light in the logo, it was not working! Sending it Back! Had problems in the past with Razer! Every time I buy something from razer the lights are always burnt out in their devices!

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.

Mine has quit working, well its sketchy it will work for a while then completely disappear from the computer only to come on randomly ( I think it is the connection or the cord where it enters the mouse.

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.

Comfortable; Good; accurate; smooth gaming performance

On-the-fly sensitivity OSD didn't work; Macros limited to 16 events

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.
