The Mionix Saiph 1800 looks and feels aesthetically stunning. In every aspect - from the packaging right through to the testing stage the Saiph 1800 has impressed. One of the features that stands out for me is the ability to change the DPI on the fly. This is really useful if you play multiple games in different genres as each game type often requires different sensitivities, its also pracical if you have your friends round and perhaps take turns on a game - you can ensure your DPI is for example at the lowest setting (blue) whilst your friend prefers a higher setting (green). The colour coding system is very useful and creates more functionality to an already excellent mouse.
