In the midst of the plastic cold steel

Right at the beginning I would like to start with the most interesting things that were perceived as negative point in almost every test or at virtually any Review:
1.) The mouse wheel will be thanks to the ungummed surface very difficult to operate.
2.) The "Mouse Feets" (Mouse skates), ie the "feet" of the mouse to quickly bless the temporal and dissolve after a few Uses Agen.

On point 1:
The scroll wheel makes my opinion a very solid impression. Despite the lack of rubber coating, which one is actually used as a gamer with mouse wheels (especially by Logitech), the wheel is very handy and easy to operate even with slightly damp fingers. Furthermore, it has in my opinion a very well-balanced resistance, which is well suited for playing games, in which is carried out for example, the "Weapon Change" using the mouse wheel (can be operated in most games also on the number block). The only Kritkpunkt at the wheel on my part would be that, where appropriate, that engage each step could be clearer. Does that mean that you tend to accidentally go 2 rotation steps, instead of just one. Possibly, however, this phenomenon is related to the Ausrastfunktion.
By the way would be to say that the mouse wheel is the only part of the mouse made of metal. In itself, this is neither negative nor positive, but you have to be prepared that the mouse wheel cools accordingly if you have not worked a few hours with the mouse.

Item 2:
I own the mouse now a day and one can argue that the mouse feet already show some signs of wear, which however, are largely limited to scratches. In my opinion, a perfectly normal development.
In many tests and reviews, there was talk that the mouse feet would flake off already after the first application at the edges, but is never mentioned on which substrates have used the mouse, users and I think that the mouse not necessarily on sandpaper and grindstones should be used and therefore the mouse feet are perfectly fine.
For reference: I use the mouse pad "Sharkoon 1337 (material-related)" and no special Logitech Mouse. Mouse I could not test the long-term operation as I said, I'll edit the post later in.

On the whole, the mouse makes me a rock solid impression and now reached price of about 66,00 justifies the mouse definitely.
Especially people with medium-sized hands and people will prefer the more severe mice find on this mouse favors.
Gaming-specific may also be mentioned that the mouse aligns more to the genre of "shooter" and the best results can be achieved in terms of accuracy, especially by the possible "Tuning" on the in-house software.

Interim conclusion:
Completely successful mouse from Logitech and strong buy recommendation for Shooter friends with midsize hands.

Edit: The mouse is now for 5 days of continuous use and is mainly used in fast shooters (eg Call of Duty), say the mouse is exposed to frequent, fast movements. So far, still no sign of wear, etc. to see. Very satisfied!
