Kensington / Kensington Bluetooth SlimBlade Pro Trackball Model Number: K72085JP Mouse PC Peripherals Includes original box and all accessories. - Compatible with Windows 7 or later (32-bit/64-bit*), macOS 10.13 or later ***Windows 11 (64-bit) only - The SlimBlade Pro has a symmetrical design and can be used by both right-handed and left-handed users. - Scrolling is done by rotating the ball, which is very intuitive once you get used to it. Used only in a home desk environment. Operation has been confirmed, and Bluetooth connection is also problem-free. Purchased in July 2024. Used for about a month initially, but I couldn't get used to it, so I'm selling it. The trackball rotates smoothly, and I don't feel any sticking. There are minor scratches from use, but overall, I think it's in good condition. I will include Bonanza (used a few times) for maintenance. If you don't need it, please let me know via message after purchase. The main body and ball have been removed and carefully cleaned with alcohol wipes. Please check the condition in the images and understand that this is a used item before purchasing. Returns are not accepted to prevent swapping.
