Logitech Trackman Marble Trackball Mouse

Very good ergonomic mouse. Uses laser to track ball movement so is very precise. New price US$149 excluding delivery. Check out review https://www.trackballmouse.org/logitech-trackman-marble/ Used it to resolve wrist/neck issue when using mouse too long during work on one hand so I swap between every now & then. Don't work anymore so hoping this mouse solves other people's same problem This mouse can be used on both the left or right hand. Buttons can be programmed as required to suit users. No chat bargains/offers/low ballers shall be entertained. If keen please make reasonable offer. Can be tested during collection if needed Thanks
