Grr. I've lost (I think) two things from my rotor - the actual button that sticks out of the back, and I think there's something that goes between that and the actual switch on the board. Does anyone know where I could get them from, or sell me spares? My kitten has chased them all over the kitchen, and now I can't find them for love nor money. It's possible she's eaten them, in which case I'm kind of keen not to retrieve them...
