In itself, it is in the mouse is a very good product. However comes with me, as with many other buyers the problem that dissolves after about 1.5 years of glue on the side and thus makes the mouse very sticky. A pity. The mouse thus is now a complaint back to Amazon (Roccat closes on the website Customer in principle from) and is well for now my last product of Roccat be. The two stars are for the really good product's having a known error (and it should probably now be known at Roccat) and poor service by Roccat.
