Covers the entire width of my desk with my full size mechanical keyboard on it and there is still plenty of space for large Mouse movements. The roccat logo is placed a bit unfortunately on the bottom right where your mouse is going to be and
disrupts the even surface therefore a little bit but the mouse pad is big enough to avoid this issue completely, it could still have been put somewhere else.
The rubber back is perfect, the mouse pad isn't sliding a millimeter on my wood desk and the thickness and stiffness of the pad is great as it can be used as a working under-mat when writing a paper or anything else.
I really enjoy the feeling of it.
