Time to plug the mouse in...

You can see that the scrollwheel and the side grip pads are lit. Nice.

When I plugged it in, Windows XP automatically recognized it.

As soon as I placed my hand on it, I instantly liked this mouse. The feel is exactly what I am accustomed to. I could immediately tell that the Krait is much more accurate than the mouse I've been using. The sensitivity was a little high, but I knew I soon could adjust that.

So, I insert the CD, and install the Razer software.

This is the Krait's dashboard. The sensitivity was defaulted at "10", so no wonder it felt too sensitive.

Sensitivity and double-click speed are self explanatory. "On-The-Fly-Sensitivity" is a cool feature. I'll talk about it a little later.

Pressing the advanced sensitivity button gets you this screen. As you can see, you can control sensitivity on both the X- and Y- axis.

The Krait has acceleration in its drivers separate from the acceleration found in XP. Though acceleration is very handy when using a 400dpi optical mouse, Razer feels that acceleration on a 1600dpi mouse will probably be a hindrance and leaves it off by default. This does not affect the acceleration found in XP, which can be turned off in the control panel.

The "Windows Master Control" shows where your "pointer speed" (Windows term for sensitivity) is set, "5" is the default. This is included mainly as a convenience... changes here will not be seen until you reboot.

On the scroll wheel screen, you can adjust wheel speed and turn universal scrolling (press the scroll wheel and drag-scroll) on and off.

Located on the "button" screen is a handy right/left handed orientation setting. Instead of having to individually change button assignments, one click instantly sets the mouse up for leftys.

There is a drop-down menu for each button. You must assign a button for On-The-Fly-Sensitivity.

On-The-Fly-Sensitivity allows you to change the sensitivity without returning to the dashboard.

Push the button you have assigned to on the fly, push the scroll wheel and this gauge pops up on the lower right of your screen. Scroll the wheel to adjust sensitivity. It takes a little practice to coordinate things, but it works well.

I have been using the Krait for some time now, so I think its safe to say that I can draw some conclusions...
