For conclusion:
Positives:
- For the price it's a good ergonomic mouse for medium-sized hands. (Size, ergonomics, key arrangement)
- The keys and the scroll wheel make yet a stable impression.
- The assignment of the keys via macros is simple and intuitive supported by the software.
- The processing is stable and it rattles nothing.
- Acceptable price for this mouse (compared to Kone XTD)
Negatives:
- The rough surface nutz however relatively quickly. (After 4 weeks already partially smooth on the thumb rest, but not too bad)
- Only 3-way scroll wheel (five I would find personally better)
Draws:
-The Rough surface is habit in need, but also has its advantages!
=> I have yet found no defects I can thoroughly recommend the mouse.
