Lightweight but strong, she slips smoothly whatever the medium. The laser is responsive to many substrates without requiring a carpet, even if it brings additional comfort. Thus the mouse works without problems on painted surfaces or printed patterns, which sometimes infect more basic models.
The USB cable length is good solid mouse output.
A flawless hardware side. Let the software:
The mouse comes without drivers, but Windows 7 installs for basic functions.
To fully customize the buttons, it will download the Logitech site the Wizard program for video games. It allows to assign functions that you want to buttons, depending on the software used. These profiles will automatically switch if desired, or you can block one profile. This works for games but also any software, which comes in handy for example to zap between tabs of a browser, or manage the tools of a word processor with a single click.
The program also allows you to choose the sensitivity of the pointer, lighting diodes (can be deactivated completely), etc. It can hardly be more complete.
No bug to use for now, the software correctly alternates profiles by customizing the mouse for each application. No not with other pointing drivers interference when using such a Wacom tablet, trackpad a laptop or another mouse alternately.
It is a versatile mouse, gamer oriented but that will suit all purposes.
Personally I like the ergonomics Evoluent vertical, but this one is very effective due to its programming capabilities as software, to provide one-click of the main keyboard shortcuts.
