What I liked:
- The pilot light and very powerful, with all the necessary options (not tested but the driver is also available for Linux)
- Product finishing (antiperspirant material very efficient, wide shoes that allow easy gliding)
- The asymmetric shape (right in my case)
- The excellent responsiveness of the sensor and buttons
- Buttons all seem very resistant to repetitive clicks and pretty quiet overall (except the wheel that is somewhat noisier)
What I liked least:
- The mouse is a bit short and requires more steering than fingertip wrist, great for FPS, a little less for everyday use
- Buttons 4 and 5 (in the thumb) are a little smaller and a little high, but it is a habit.
In conclusion: in form, I prefer the Razer Deathadder; for the rest, the Roccat Kone Pure is a notch above. If the size of the mouse is a problem, there is also its big sister: the Roccat Kone XTD, but is also a bit more expensive. Otherwise there is the model below: Roccat Savu of which has a size between Kone Kone XTD and Pure.
