The included disc installed the program, which allows a very simple configuration of the mouse to your own needs.
- The mouse has 4 speed levels that are turn on by the center key.
- Each of the 4 stages pulsate in another Frabe (red, blue, green, pink)
It is thanks to the program easy held very easy to customize the mouse to your own needs.
I for example. Did not need extremely slow level and have generally increased every Geschwindigekeiten. Additionally, I have assigned the new colors. Within 2 minutes.
The processing is free of defects, my hand sweats little and does not slip and especially I'm surprised that the mouse works excellent manner without a mouse pad on eg tables.
Overall, I am pleasantly surprised and did not expect to get such a good mouse.
Strong buy recommendation!
* EDIT *
Have this mouse can buy for 20 Euro. For currently 43 there is no overriding value for money, but only 'good'
