The Razer Diamondback is an unbelievably sensitive mouse. I need to get that out of the way right now, because if you are not used to having high sensitivity settings on a computer mouse this thing will fly off the screen with just the slightest movements. This is amplified even more because of the mouse’s weight, or lack thereof. It is by far the lightest computer mouse I have ever used, and also the sleekest.

It seems the concept behind the 3G was having more control over it then using it as a controller. While some people like heavy, sturdy mice with lots of buttons and options, the Razer Diamondback isn’t about that. Your hand is in control, not the mouse.

I don’t know how I feel about it. On the one hand, it does feel like an extension of my arm and moves quickly and accurately. It feels smooth and its symmetrical design is very comfortable. On the other hand, I do enjoy a mouse being like a controller and having a nice, heavy one gives better accuracy in some games. It really all depends on your tastes in this case, and for the price I would recommend this mouse to anyone in the market. If you are looking for a gift for that special someone and they are a PC gamer still rocking whatever came with their machine, this is a great gift.  Here is the official website.
