Whatever you do, don't mistake the Genius Wireless Pen Mouse for a replacement for a Wacom Bamboo Pen & Touch graphics tablet, or even Genius' own G-Pen M609. This isn't a device for graphical artists to replicate their brushstrokes on the computer, and if you bought one thinking it was, you'd be disappointed.

What the Genius Wireless Pen Mouse actually is, is a pen-shaped mouse. Dragging the tip of the pen across a desk, we were able to control Windows pretty well. Pressing down on the nib replicates a left mouse button click, and there is another button on the shaft for right mouse button clicks.

It works rather well, with the familiar shape of a pen allowing you to get used to the new input device pretty quickly.

We found that the Genius Wireless Pen Mouse is best suited for working on large and multiple monitors, as you can move the cursor from one side of the screen to the other quickly, in a small space. You might find the Genius Wireless Pen Mouse a bit over-sensitive when you first use it, with its 1200 DPI sensor, but changing the mouse cursor speed in Windows can make a big difference.

It's a device that works well, and we can certainly see the appeal of it. It's not quite good enough to completely replace the traditional mouse for most tasks, however.
