This is a good mat with a quick sliding surface, almost as That a razer goliathus editing speed. The design one likes or dislikes. But as goliathus speed, the surface is too matte. The sensor of the RAT 7 (2013) tends to "jump" in office. I do not have this problem with a carpet type matt goliathus edit control. In games we do not feel it "jump" of the sensor, it is primarily in office. Quite disappointed that carpet the same brand as the RAT does not fit perfectly to the sensor, is the limit! I let the benefit of doubt to the quality of the mouse sensor, be careful if you know that your sensor is somewhat .. difficult. Like other reviews, I think the packaging is really too small, the carpet is compressed and retains a curved form, leave a few days before your encyclopedias and other larousse to make it usable, expect a small delay before use;)
