I’ve had one of those for a couple of years - love it, especially the little button so you can have clicky scroll or it freewheels when you spin the scroll wheel.A mouse. £35 off amazon. Im fed up with cheap mice. It has a nice feature, press a button and it will connect to another device with 3 saved. It works on phone and tablet bluetooth too.
