Now the not so good:
The thumb buttons are ziehmlich quickly "Swallowed" and not always react. And after after about 9 months of the sensor is broken. In 5-10 hours of daily use no problem.
The very bad:
The service of mobile Dortmund (The shop where I ordered the mouse) is abysmal. I wrote to the store and was referred to the Cyborg Support. This would have nothing to do with the matter, as in the case of failure of Hänlder is responsible. So I again wrote to Dortmund phone and made some steam. I should move to another store to send the presumably a kind of partnership with mobile Dortmund (a pure Internet company) has. That's what I then did. 2 days later I received an email in which I was informed that I would be just as it is getting sent back the mouse, as you could connect to 20 times will not understand the error several hours.
Today I again get the mouse and less than 10 minutes after start-up, I had the same error as before. To this was then that the mouse was packaged grottig (so that a broken cable would have been no surprise) and the mouse has become much dirtier. In addition, you have already viewed the package as it has been treated "well".
Conclusion:
Top mouse, Hänlder flop. Best buy of the manufacturer's website or in the media market around the corner.
