Purchased in 2025 from Amazon (used approximately 4-5 times), I bought this item in excellent used condition. I used it for about 1-2 minutes, but it didn't suit me, so I'm selling it. Unless you are extremely particular, you'll likely feel it's in like-new condition. Includes warranty, wireless receiver, batteries, and all accessories. ◆ Product - Brand: Logitech - Model Name: ERGO M575S - Type: Trackball - Switch: ON/OFF switch - Color: Black Please ask any questions in the comments.
