I've been using it for about a month. I've replaced the mouse feet with QSPEC ones, but I've only used it for about 20 hours, so there are no scratches or stains, and of course, I've confirmed that it works. I offer same-day shipping, so if you purchase it, please let me know your preferred delivery time. I will ship it from a Yamato Transport sales office. The lightweight and high-performance gaming mouse, PRO X SUPERLIGHT 2, is designed for esports. - Model Name: PRO X SUPERLIGHT 2 - Brand: logicool - Features: Q.SPEC, BORN FROM ESPORTS Thank you for looking.
