now I have this Kova + discarded mouse brought my old Logitech back out of retirement.
why: the lateral rubber coatings (left and right) are glued to the mouse. that's eigentlicht not so bad, but the adhesive has begun to liquefy, when you hold the mouse a little longer in the hand. apparently this is enough already of the body temperature. The result was that the glue was on the edges to the surface ... and it thus had on the thumb and, on the other hand, the small- and ring finger liquid adhesive residue. an absolute absurdity, not even a mouse 5euro China has something !!!
the second disaster is the mouse wheel. at the beginning (about the first month), it was working fine, but after that it began at a certain position to squeak ... squeak now throughout !!!
Although the products from ROCCAT look very chic ... but after my number comes from this manufacturer nothing more into the house.
