Haptics / processing: for my rather large hands it is, because of their shape quite well suited even over long periods. But everyone must try for yourself. But in the choice of materials it comes with the criticism going on already. The rubber coating on the sides is quite rough and feels uncomfortable and cheap. Compared to the Emperor, which has a smooth, soft-touch rubber coating, this makes for quite sweaty fingers. In addition, they had to be exchanged twice because the keys have too rattled factory. A strain relief for the cable you are looking for in vain.
Gaming capabilities: Go to my mind to 0. The laser makes me problems, there are times where it is suddenly much too sensitive, as if would the DPI value for moments of self-adjust. The DPI buttons are not pressed. And if they do, the mouse behaves quite differently.
Mouse Wheel: This point must be emphasized, since it is what also concerns the G400 and probably the G500S and G400S a series errors. Undzwar this is operated after / during the scrolling again and again after a certain time interval again, sometimes even in the opposite direction. This manifests itself in the fact that, for example, will be moved in the web browser the image back up, although one scrolls down. Or playing the weapon is changed without using the mouse wheel - which is especially the middle of the battle very annoying. This problem I could see with 3 copies of the Logitech G500 and 3 copies of the G400.
The final knockout Kritierium is the infamous buzzing, which comes from the direction of the well so already failing mouse wheel. It is extremely loud and even from several meters away perceptible. Once you move the mouse, the frequency changes or silent places.
Conclusion: Stay away, even with the followers has at least changed nothing on buzzing!
