Hell of a creak, even when you just put your palm on the mouse. The back bends even with a slight pressure. No luck, in general. If you press the back harder behind the DPI buttons, then you can achieve the operation of the buttons. I recommend to check when buying by clicking on the top. On others (Mamba Chroma, DeathAdder of previous generations) there was no such nonsense =\ The mouse was bought only yesterday, but I doubt that it will be possible to return it under warranty with such "nonsense" =\
