Muggle-Born-Detector and Sneak-O-Scope not working anymore

Support Ticket

My Muggle-Born-Detector and Sneak-O-Scope don’t seem to be working anymore. I’m not sure why but it might be because I removed them from my office when they weren’t actually working (I saw some of these devices working again now and when I went to place mine down, they weren’t actually doing their thing)

Request for Solution
If possible I’d like to get them fixed/get replacements (as they’re quite expensive)

ask an owner to take some back up ones from my office and help you replace them
