The IntelliMouse Optical incorporates all the great features of the IntelliMouse Explorer mouse into its design--optical technology, cool red underglow, titanium accents and superior performance. It also answers the most common complaints about the Explorer. For example, the two troublesome side buttons that were on the Explorer have been moved--there is one on each side of the IntelliMouse Optical, so both right- or left-handers can now program and use these buttons for any number of functions. In addition, the IntelliMouse Optical's smaller body is comfortable for people who don't have large hands.
Installation is quick and easy. The IntelliMouse Optical plugs into your USB port or into a PS/2 port with the included adapter. It comes with IntelliPoint software for both PCs and Macs so you can program the two extra side buttons and the wheel button. Once you have set up the buttons, the mouse is ready to go.
Just like the Explorer, the IntelliMouse Optical works on most surfaces and doesn't require a mouse pad. It is possible to use the mouse on a wood desk, stacks of paper, a trouser leg, the carpet and other non-reflective surfaces. Don't try to use this mouse on a glass desk, though--the IntelliMouse Optical needs to be on an opaque surface. The optical technology works by taking 1,500 pictures per second of the surface beneath the mouse and instantly comparing the series of pictures to track movement across the surface.
We also enjoyed using the IntelliMouse Optical for gaming. It's super-accurate and quick to respond. And the scroll wheel is tight, making it easy to select weapons. Whatever the application, the IntelliMouse Optical is a great mouse with almost no flaws. We highly recommend it.--Ara Jane Olufson
