The Dark Matter Rover is a perfect entry level mouse if you are looking for better optical reaction in your control but do not need extra buttons for specific gaming needs. I use this mouse at work to give me better precision while working on digital drawings. A typical mouse will have me fighting to get to that exact spot I need to be, but the sensors on this one are accurate and never leave me questioning if I can draw something correctly on the first try. This is a great mouse for the price and I have no issues with it.
