Negatives:
- The Achilles heel of this mouse is not available, the 4-way scroll wheel. The pressure on the mouse wheel was supposed to trigger the middle mouse button or another programmable function, but unfortunately is far too stiff and it is often the scroll edge mitausgelöst left or right. Therefore, the scroll wheel is not to be used as a middle mouse button. Here can be found on the mouse is no more easily accessible button that could take over this function.
Another problem is the fact that the scroll wheel on the top is too smooth. If you want to the left or right press the scroll wheel so you slide on the top off frequently. To reliably must trigger the Left or Right scroll, one on the left and right side of the wheel "embrace" with the middle finger and only then press the wheel from the side.
The scroll wheel can be unlocked while, but the release button is on the bottom (!) Housed the mouse where it is not available in the mouse operation.
Im not unlocked state, the wheel scrolls Although precise, this is but unsightly, excessively loud scratching noises which bit annoying.
When unlocked, the wheel scrolls virtually free-running, without noise and simply great.
For durability of course I can make no statements and will also make no because the mouse is returned.

Conclusion:
If you omit the mouse wheel in the consideration, one would get a good to very good mouse, if not 5 star would earn at least 4. Unfortunately, however, the mouse wheel the ultimate Achilles distance to the mouse. It makes sense and ergonomically can only use the scroll function and particularly the freewheeling function. If that is enough, which is well served with this mouse, all other I advise.
