Please read the profile before purchasing for a smooth transaction. This is the "Logicool G600," a legendary multi-button mouse highly favored by MMO gamers. Its main feature is a total of 20 programmable buttons, including 12 side buttons that can be operated with your thumb. In MMORPGs like "FF14," you can activate numerous skills and macros with just your hand, without using the keyboard, dramatically improving your play environment. It's a wired (USB) connection type for stable communication, and the cable is a durable, fabric-wrapped design. 【Condition】 This is a used item that has been actually used. There is no significant damage, and it can still be used as a practical device. All buttons have been tested and confirmed to be responsive, with no chattering. Please check the photos for details. 【Recommended Points】 This is the perfect device for those who "want to make skill rotations easier" or "don't have enough fingers for keyboard operation." In addition to gaming, it's also an excellent mouse for improving work efficiency by registering shortcuts for video editing software or "copy and paste" functions in Excel to the buttons. How about it as a spare or an entry-level multi-button mouse?
