Open packaging, supplied AA battery in, mini-radio receiver plugged into the USB slot, below the ON-OFF button is Unlock, 2sec later the mouse pointer moves! Without any installation! I can therefore also the recipient to any other computer (eg university computer, netbook girlfriend, ...) and you're ready.
Another practical feature is the gray Shift up behind the wheel. There you can the resolution between 800 and 1600 DPI switch. I use the normal operating 800 DPI, but if I am, for example in bed with the laptop, I can still use the mouse on the narrow edge of the bed, by I switch to 1600 dpi and thus need less way to the pointer from edge to edge to bring. :)
I have pretty big hands, but the mouse is wonderful in his hand. The two thumb buttons are also stored under optimal conditions, without pressing accidentally. I often raise the mouse with your thumb and little finger, but unlike my previous mouse I've never come accidentally on a thumb button.
Clicking sound, mouse wheel feeling, etc. are also top. And the battery indicator on the left thumb buttons I have not yet used, but other reviews say the battery lasts a long time. will see...
The only: because supplied with any software, you can not freely define the key. At least I have not found a way under Ubuntu. But because the default Back / Forward is eh, I do not need that, too. Exactly this function I need always.
Conclusion: highly recommended! Würd buy again at any time! (Also because of the practical on-off switching function in the ground to save energy!)
