The resolution of the mouse can be changed on the fly to suit your needs from 240 to 4000 DPI (manufacturer data) by lintermédiaire 4 different default choice changed course via Logitech interface.
The right and left clicks are processed quickly by embedded electronics, IR motion sensor is excellent (tested on wood, laminate, mouse pads) all without doubt helped by the timing 1000Hz (millisecond) information on the port USB.
I regret that the USB cable is not (for that price) woven as the G502 model, japprécie this type of cord for their high robustness and excellent performance for mobile use.
To: lightness, the overall finish, the design, the intrinsic quality of the product.
Against: information limited to the simplest terms, the price compared to the G502, non treissé cord as the G502.
Conclusion: You will need to download the software "Logitech Gaming Software" to configure the mouse at will to enjoy it fully. However, at 60, even if the mouse is a good product, I have great difficulty in completely memballer probably because he has ny (when I write these lines) less than 6 euro difference between the G402 and its big sister G502
