First the positives:
+ Mouse wheel is very quiet
+ Rubberised surfaces on the sides or elsewhere which, though touted for their grip bring (by manufacturers), but in my opinion not purported to improve and collect only the fat from the fingers, which is not so easily comes off the rubber surfaces again
+ So far the mouse has made use extent easily and makes a good overall impression
For negatives:
- The on-off switch is to use something hakelig
- The main problem is that the sensor is quite inaccurate. For people use the relatively slow Zeigergeschwinigkeiten that should dastellen no problem. People, but the use of a quick setting that will surely interfere. I use a medium to fast setting and with me it's borderline. It's simply felt that the mouse jumps several pixels, which I'm not used to my old M325 Logitech. Whether I really characterized
Cast. makes the mouse a good impression for the price, but the sensor is not convincing really. But I will keep the mouse anyway, because you can still work and play well with her.
Edit: I've now worked more intensively with the mouse and unfortunately had to find that working with programs that require precise input (AutoCAD) are quite a patience thing. For me personally, the mouse, making it only conditionally suitable and I'll probably buy myself a new mouse because stressful work so quickly is an ordeal. However, there is still that the mouse for people with slower mouse settings and less precision required (surfing etc.) should still be good enough. Nevertheless, for my part, a depreciation of 4 to 3 stars.
