Read So smart and came across vertical mice.
The Delux M618 was after less than 24 hours with me, what I ever thought was very good.
From feeling it, than if you try to move a joystick mouse is.
One thing the Gewöhung I guess.
What bothers me:
If you completely rests his hand on the mouse body, the keys are not under your fingertips, find more under the palm up close phalanx. That bothers quite the click and while gambling.
However, I must add that this mouse has led tatsähclich already an improvement!
Therefore 4 stars
