Gaming mice have certainly come a long way from the early days. Back when mice were mainly used for pointing and the thought of having a dedicated one for gaming was merely a dream of Thresh, the way that manufacturers differentiated their gaming mice from the regular sort was to make them optical, black and add a click-able scroll wheel. Time rapidly moved on and optical mice were overtaken by laser mice, but still the "all black with loads of buttons" ethos continued. Indeed some mice are so bloated with buttons that it's become tough to find a way to hold them that doesn't lead to pressing 6 different ones at once. Thankfully companies have realised that what we really care about is having an epic sensor, perhaps a couple of extra buttons and comfort. Ergonomics often lead to mice being the curved shape that best suits right-handed people, which has meant that southpaws, and those of us who don't want a banana on a cord, have had a very short list to choose from for our new mouse. Enter the SteelSeries Sensei. An ambidextrous sleek affair that concentrates mainly on customisation and comfort, whilst following the modern minimalist design school that is so popular.
