My current mouse is from Razer (Naga Epic) and I only play role-playing games.
I'm using 12 thumb buttons so accustomed and would never want to play without.
Since I still have a notebook in which I also play, I wanted to test the G600 here, because otherwise I only Logitech products used and in the past also had exclusively Logitech mice.
In a nutshell: I could not cope with the mouse.
The workmanship is indisputably very good, the mouse feels valuable and also the Ergnomie is the pure "laying on of hands" very good.
To use the G600 for me personally falls behind the Naga Epic.
Compared with the Naga Epic, the 12 thumb buttons on the G600 for me are to achieve significantly worse. I've certainly not the biggest hands, but particularly "small" I would not call my fingers.
I had to reach the top figures (G11 / G14 / G17 / G20) "put his hand slightly, what I felt in the long term as unkonfortabel.
The Naga is here simply just a tad bit more intuitive to use, because the buttons are minimal deeper.
Also, I found the 3rd mouse button (G-key) annoying as I have constantly triggered accidentally.
I tried to get used to it and tried to realize my fingers store so that I do not actuated the key, but in hectic moments I have now and yet again and again pressed the button.
If you have previously not possessed any MMO mouse, you can quickly get used to the G600 certainly.
For me, however, it is clear that I am lifted significantly better in the Naga Epic Razer Naga Epic and would prefer the pure compared to the control (more differences in equipment etc. sidelined Gelas) the G600.
Without G-key and with minimal deep-seated thumb buttons the G600 would have my mouse.
