It is not the best mouse out there for things like gaming, but if you are looking for a general use mouse that adds features not available with a PC mouse on a Mac and want a mouse that is reasonably priced (compared to Apple's Magic Mouse) then this mouse is for you.
The only problem with the mouse is that it can be tough to push the side buttons and a wired mouse as ever remains a bit of a nuisance with its more limited range and placement options compared to a wireless mouse.
The best feature of the mouse would be its scroll wheel / ball which makes it easier to scroll both vertically and horizontally compared to most PC mice.
