The processing is for this price range more than okay. The weight is appropriate; not too light, not too heavy. It squeaks nothing, all buttons are within easy reach and the glossy surface feels - contrary to my fears - very pleasant to. In general, the mouse in my opinion is very good in the hand (but I have pretty small hands).
I have it on different surfaces - tested and could no dropouts, hoppers or other disturbances notice - tabletop, paper pad, mouse pad, etc.. Everything is very precise and fast.
I'm going to the mouse but still return as it my feeling has one serious flaw: The keys can be far too easy press.
I have really no dustbin lid-hands and still clicks particularly the right mouse button already at the mere filing of the fingers, which - can be incredibly annoying - especially with games.
Of course, this is also a matter of getting; I knew it from my old Trust mouse just so that I could take the hand comfortably on the keys.
Who this "error" does not interfere with - and who uses the mouse rather for work and surfing because for gaming - who gets here a very pretty and well designed laser mouse for little money.
