Amazon.co.uk Review
The mouse connects via USB, though a PS/2 converter is also supplied. The package comes with Intellipoint 4.1 software and is straightforward to install. It works with Windows 98 and all later versions of Windows. It's also compatible with Mac OS 8.6/9x/10.1. Unlike traditional mice, the Microsoft Blue Optical Mouse doesn't contain a ball. Instead it uses a high intensity LED and optical sensor to detect movement. This negates the need for regular cleaning and also provides greater precision.
During testing, the Microsoft Blue Optical Mouse performed well. It's comfortable to use, and precise. The buttons and wheel are responsive and accurate. Combine this with the durable construction and you have a mouse that is well worth the investment. --Jason Weston
Manufacturer's Description
Optical technology replaces the old-fashioned mechanical mouse ball and works on virtually any surface, meaning accuracy will not be lost due to wear and the accumulation of dust and dirt.
Instead, Optical Mouse Blue uses an optical sensor which scans the surface beneath the mouse and accurately tracks the mouse cursor movement.
Optical Mouse Blue features blue detailing, Microsofts signature glowing red underside and taillight, and ergonomic enhancements to provide comfort for left and right-handed users.
