--- Size & weighting- mouse ---
The size of the mouse fits pretty well with me. Is nice in your hand and the buttons at the top and the left can easily be reached.
For weight you have to say much, since you there it myself with the small weights can adapt (4x4g + 4x7g) itself. I have currently two 4 and 7 Series two weights in it.
--- Appearance ---
The design of the mouse is also really great. The two supplied handles are also really cool. The gray is smooth on the surface and the black is corrugated.
--- --- Buttons
The buttons are so far also all well placed, only the back and forth button you would have a left and the other can hinmachen right, but otherwise really great.
From what I'm excited really, is that you can adjust the speed of the mouse in 5 stages itself. So you can, for example, in a shooter as Sniper adjust the mouse slowly and as Assault faster and go the extra zumüssen in any settings.
--- Conclusion ---
Real super mouse, a little high, but still justified price. I can only recommend.
