The beginner / casual gamer mouse

I had now for nearly 10 years a MX-518 by Logitech and now had to get replacement after that had given up the ghost to me.
In the meantime, I had tested some mice between 20 and 70 euros and was not really satisfied.
Since I really only now and then sit at the PC and there will not even great on a tight budget, I have chosen the route Perixx Mouse - and am really happy.
She is a bit like the Logitech MX-518, but the technology is still a little new and the mouse is a little heavier (plus for me).
The mouse is really great and I now want to carry out any for ages plus-point list, I write on only two negative points that could be improved:

The DPI settings are adjustable only in 500 steps.
For each DPI setting the mouse lights up in a color. You can switch between 5 settings. The settings are independent. However, you can not adjust which color belongs to which setting - pity.
