I have to test it with a colleague, so I knew what to expect.
Before, I had a Razer eXactMat Mouspad, also each with a speed / crontrol page.
With the mouse pad from Razer, I always had the feeling buzzed the dust particles between the laser back and forth, or the mouse
possibly had a defective because the mouse is "jumped" more often. Although only marginally but me as High Waldensian
it has often disturbed. I had a Razer Imperator and now I can call the Cyborg RAT 7 my own.
Since then I have the Alumic, there are those little "springer" (as described above) no longer!
For me personally, there is a difference like night and day. Because of the quality and the fact
that the pad is made of aluminum and thus maintain yet easy to clean years, I can fully satisfied
5 of 5 stars awarded.
