I want to write here any complete review, but only to say something about the reviews 2-3, is where grumbling about the lack of precision: At first I was also very unhappy that the precision were concerned, it seemed to me as if the mouse pointer 'jump' on the screen and not exactly reflect the movement that I have done with the mouse. It took several attempts to even partially buttons to hit to websites, which of course was unacceptable. Poised to return the mouse to switch to another seemed to me still the idea to try it with another pad. So buy the electronics market for 5 on the off chance a pad that is 'suitable for laser mice', according imprint and behold: Everything is working fine! The mouse works now absolutely precise and reliable, I'll meet each pixel in the CAD program and in games, there are also no problems. The only thing I had to get used to was the surface of the new Pad because it's a lot smoother than my betagtes Everglide Attack Pad. But ne thing was 3 days, now I am very satisfied with the device and can highly recommend (the same pad or corresponding document provided) each!
