The unofficial successor to the Logitech GPRO, the G203 / G102 is a cheaper but very nice alternative. The only difference in the 203/102 name is what region the mouse was sold in, however both models are in fact the same exact mouse. The sensor isn’t the same as the GPRO, this time around Logitech opted to use their own proprietary sensor called the “Mercury”. Testing of the sensor has shown that it operates almost identically to the GPRO’s PixArt PMW 3366, so that's great news as it’s one of the top sensors on the market. The mouse is quite small in shape and light in weight, making it a great fit for gamers who like to pick up the mouse often during gameplay.

Professional players currently using this mouse include: Mithrain (PUBG), Bryan (Rainbow Six Siege).
