Roccat Kone Pro Air wireless mouse (third party seller)
Deal Score0
€ 39.89 – Amazon
Mouse that has a few years now but that remains the best mouse I have had. The grip is perfect for right -handers, the materials make it light (without being a feather, however) and sliding is really good.
Possibility to completely deactivate the useless RGB.
The battery fits more than a week without problem with use 10am/day.
Some will say that “XXX did better lighter blah” but for 39 €, it's really a very good choice!
