Thanks for messages. The eject button was sadly no use as it hadn\’t been \’armed\’ by fully inserting the card. And bizarrely I couldn\’t find a paperclip – seemingly not popular in remote Chile – but I did similar with a leatherman blade and eventually it came free. I\’m surprised the design allows this – it\’s alarming to think you could damage the slot in such a simple way – but I\’ve learned my lesson!
