@paul@tapbots.social I’ve used the Kensington trackballs for as long as I’ve owned a PC that used a mouse. When they started doing optical tracking and the “scroll ring” I bought extras just in case they ever got discontinued. https://www.kensington.com/p/products/electronic-control-solutions/trackball-products/expert-mouse-wired-trackball3-1/
