Have the mouse pad quite long -only just ran across it at Amazon randomly, so I give ne vote off and use it well still, but there are better. To me it is actually too big or I do not need nearly as much pad (why are all "gaming-cards" XXL if any clever player plays with ner endssensiblen mouse setting ....); but good, large dimensions were known (22x38cm, 28x40cm not as advertised!). It is well made, did it already 2 years and it know virtually no signs of use. My Razor Imperator scans it tadelos from (high dpi) ... when the mouse not on white spots OF THIS DESIGN IS !!! Laser have simply scan so a problem such bodies, you can see immediately that there is no discernible the roughened surface already with the naked eye, the light is refracted not good at it. Dumber is Nimmer's. I use it nevertheless continues because my mouse is so sensitive that I can move the mouse exclusively in the black area. Do not misunderstand, the bright spots, it is also, at the latest at the completely white bow cross the mouse on the screen stops short / is delayed. This makes not only a playing narrisch.
Therefore: To be a good mouse pad, but ne Kaufempehlung you can not give because of the aforementioned problems actually.
