If you think that an E-sports mouse such as Logitech g Pro x superlight is light enough, only 63g, you might as well know that the world's lightest mouse, m2k, made by the German company zaunkoenig, weighs only 23g. YouTube optimization tech recently tested this mouse. It home learned that the shell of m2k is completely made of hollow carbon fiber, the contact area is only half of the traditional game mouse, and the length is only 79mm. Therefore, this mouse is very small and requires fingertip grip, because there is no place for the palm to rest. Although its volume is small, this does not mean that its hardware is poor. Its left and right buttons use the Japanese Omron d2f01f microswitch, which is one of the lightest switches in the mouse today, very close to the ultra light switch used in Logitech g303. Due to the pixart 3360 sensor, the m2k also has the highest polling rate among modern game mice, up to 8000Hz. Razer Viper 8K Hz and Corsair Sabre RGB Pro are the only game mice with the same polling rate. According to the optimization tech test, the end-to-end delay of m2k is only 13.5ms, which is the lowest at present. According to optimization tech, he found that when he aimed in the competitive FPS shooting game, the m2k performed better than the mouse he used before. He even said that it was the best mouse he had ever used. However, m2k is not cheap. Its price is as high as 300 euros (about 2115 yuan). It is one of the most expensive mice in the market, and its price is twice that of the flagship mice of Logitech and other brands. (Xinhua News Agency)
