Sensor cruel, rest well

A while ago I bought this mouse on another website and was also completely satisfied: good features, good ergonomics and good keystrokes.
After I though to my Grafikkarrte a Zowie FK got and they tested a while I noticed on my return to Sensei how incredibly bad, the sensor is of this, he reacts delayed and spongy and behaves generally very unappealing.
Can I recommend this mouse? NO, for the price, the stay away and would rather buy a mouse from Zowie as they offer significantly better performance for less money and we noticed the need a fast response time, on Results (CS etc.).
If anyone, however, can ignore the fact that the priorities are set completely wrong, you set the appearance of the performance and fairly slow plays he can feel quite with the behavior of the sensor, the befriend causes a strange "soft" move the cursor, I can not do this.
