Elecom 8-Button Large Trackball Mouse HUGE Wireless Type Purchased in January 2025. Used for about a month, but I replaced it because it was too large to carry around. Usage frequency was low, about an hour a day at home for checking emails, so the click feel, connection, and operation were all problem-free, and the exterior has no noticeable scratches or dirt. - No drops or water damage. - No pets or smoking. ◎Included Items Same as when new. - Main unit - Receiver - 2 batteries - Box and instruction manual Many buttons made copy & paste and tab switching very convenient with one click! Although it's large, it's a trackball, so it doesn't require much space, and it was convenient to operate on my lap or on top of the printer. ELECOM black and red trackball, convenient button layout, and batteries included. - Brand: ELECOM - Model Name: Trackball - Color: Black/Red - Included Items: 2 AA batteries - Features: Convenient button layout Thank you for looking.
