I bought one of them usb ones too....but it is a pain trying to set the lap top in the room with me hold the microscope still...just a pain.....i bought a cheap pair of glasses that have a loupe on both eyes and both have a little led light....can only use one side at a time but it allows me to stable myself with both hands and get in close....i get to shaky holding a jewelers loupe and trying to balance myselflol its a sight to see
