Software does not realize the profiles, you have to constantly reload the saved profiles
Mouse has become unresponsive, Courser hooked, jumped. Unplugged mouse, re-inserted, now it works again.
At a High Premium 100 Euro mouse, I expect a guide, so that I can operate the functions. It can not be that I have to carry a rain correspondence with the Support to find the key assignments and settings out.
The fact that the software the stored profiles are not reserves, special you have to load it again and again, is annoying. Quality and reliability look different.
The Finn is an innovative and (for me at least in one direction) good usable extension. The new analog switches are ok. It is missing here in supporting the Games or I miss a BF4 preset set, especially Roccat is applying the new key to the game.
The mouse fits comfortably in your hand. Moving from my Logitech MX 510 (for years a loyal warrior) was used to, the new buttons, however, are quite helpful.
Yesterday, the mouse was no longer to use the middle of the game at once. The cursor hung and left movements hardly or not. After tests, the profiles to reload brought a training and then have the option to continue playing plugging the mouse.
For 20 euros, I would have said nothing. At 100 euros those negative points are not acceptable.
