Design
The design of this mouse has a unique look that is certainly going to catch one's eye as a notebook mouse.  When looking at the mouse, it has a nice curve to it that gives it a refined look making the product look expensive.   The sides of the mouse are covered with a black rubber grip making it easy to hold onto the mouse.

At the top of the mouse, there is a scroll wheel  that is capable of tilting to the left or right for functionality.  There is also a button right below the scroll wheel.  At the top left of the mouse, there is a zoom switch that is ideal for zooming in pictures or documents.  And in the thumb area on the side, there are an additional two buttons.

At the bottom of the mouse.  There are sliding surfaces at the key corners of the mouse.  The larger gliding surfaces are towards the top of the mouse with the smaller ones towards the bottom for support.   There is the battery compartment, the hole for the laser which does the tracking of the mouse, a "microgear" switch, and a power and eject button.

This mouse uses a single AA battery as its power source therefore keeping the mouse lightweight.  The power button is used to turn the mouse on or off.  The power button allows you to power on the mouse or turn it off.

The more interesting feature is the "microgear" switch at the bottom of the mouse.  It changes the behavior of the scroll wheel.  When switched to one side, the scroll wheel will have a notched feel.  When you slide the "microgear" switch to the other side, the scroll wheel will have a fluid, frictionless feel making it very easy to scroll through very long documents very easily.  You will need to lift the mouse and switch the button everytime you want to switch back and forth, which might be a hassle for someone who wants to take advantage of this very frequently.

The eject button underneath the mouse is used to eject the usb receiver/transmitter.  The receiver is very small preventing it from sticking out too much in a notebook computer.  When you are done using the receiver, just remove it from your notebook and store it back in the mouse.  Therefore, the only thing you need to carry is the mouse itself.  There are no additional wires or pieces to worry about.  The receiver/transmitter uses radio waves at a frequency of 2.4Ghz in order to communicate with the mouse.

Performance/Comfort
As with any mouse, switching from one mouse to another can sometimes be uncomfortable since you're used to your previous one.  This mouse did feel slightly awkward at first, but after a few hours, I was comfortable in using it.  Since this is a smaller mouse, there is less support deep in your palm, but the mouse gets the job done.

I tested this mouse to reflect on how well it performs in various activities.  In basic tasks such as browsing the Internet or looking at documents, it was very easy to switch back and forward between web pages as well as navigating long documents.  The side buttons on the mouse are firm to the touch, but easy to press.  The scroll wheel provides a nice gentle feedback to let you know how much you have moved the scroll wheel.  Even when switching the mode of the scroll wheel, the frictionless wheel responded well in scrolling through long documents.
