I want a wireless mouse for my laptop but also want to put the same mouse on a pc sometimes, do all wireless mice work on laptops and also pcs?

Yeah...aslong as there is a usb connections for the usb blueth device to plug into your pc/laptop. you would just need the drivers although if the mouse is usb (which it will be) it will more than likey be plug and play so just plug it in with charged batteries and off you go
