Extremely robust and durable

I have this mouse pad now for well over 2 years with a dark blue surface.
Despite extreme conditions with frequent hours of continuous use, there is so far nothing to complain about.
The gel pad is indestructible and keeps well before an elbow out.

Leakage and deformation? None.

The mouse pad is also now temporarily still operated at the beginning and with a ball mouse.
In between came an optical mouse for use.
For about 6 months a laser mouse is used.
So any kind of mouse works completely free of errors.

Positive aspect is also the ease of cleaning of the pads ... running water, nail brush and soap to the gel pad harm and dried it with a towel quickly.

Adhesiveness of the pads is ensured at all times and at all (dry) surfaces.

All in all, for continuous users highly recommended.

Against the size of the working surface for the mouse I can not say anything. Simply mouse speed increase and ready.
1.5cm movement in all directions in order to reach the respective end of the screen thanks to laser mouse no problem :-)
