Good, but worse than its predecessor

3 stars are perhaps strictly speaking "too little". Because it would have to only once elsewhere give an overall better mouse, at the same price. And there's not (probably); I know in any case no.

But wait - the mouse that I use every day intensively since about 3 years now, the Logitech 'MX Revolution "(ie the previous model), it seems to me, in fact, as" better ". What is it better?

Primarily, it is the scroll wheel, which in my opinion, much functional working in the "revolution", by requiring no explicit switching between the easy snap, precision scrolling, and the lightning-fast scrolling. At the same time one has unfortunately clearly stated that the new wheel has a less solid. Even the the "revolution" had at lateral movement a spongy feel, the wheel of the "performance" now has nothing more that could be called a pressure point.
In this respect, I find it also difficult to evaluate "Wieger won" middle mouse button as a major asset for the functionality. When a print to this "key" inevitably conjures up concerns how long the underlying mechanism may think well, I have personally in any case not want to operate them more often ...

Not very much confidence in the longevity also arouses the "cheap" clack end switching button is switched to the between the precise and fast scroll mode. The - in comparison! - Skeptical provoking impression continues with the normal mouse buttons that are easy act already in new condition "shaky".

Is it as bad as it sounds? No, the formulations are necessarily somewhat exaggerated. It's all about me, listen to the right for me clear overall impression that the new Logitech is less solid than the old one. And of the functionality forth in my eyes also certainly not better - except for the software, which now offers even more ways to trigger functions via the various mouse buttons, such as the very practical for me to adjust the volume.

In short, the Performance Mouse is certainly still an ergonomically successful, practical and noble mouse, for which there undoubtedly are not many comparable alternatives. But my opinion is obtained for "more" money to less tangible value than the outstanding predecessor. In particular, the Mausradmechanik makes me not very long-lasting impression.
