the sensor is really good, it didnt skip'd yet with a very low sens . ( 55 cm/ 360 ) but im playing with 28cm/360 atm . 800 dpi / 1000hz
With palm grip, this mouse is really good . i used wmo 1.1a, kinzu ( but sensor is shit), abyssus and zowie FK before this one, i can say its one of the best ambidextrous mouse.
The cord is really flexible and you dont feel it at all.
I will just add some other mousefeets because the razer's arent enought thick and mouse does not slip as it should.
