[RIPE Atlas Ambassadors] How to get people to actually plug in their probes?

I had a conversation with a new probe host who was wondering how many of the probes I hand out "walk off" never to be seen again. Sadly, that's quite a lot of them in my case. I guess I need to find conferences with more reliable attendees? People promise to plug them in but then they get distracted. Or they move and the probes end up in boxes. How do other ambassadors twist their hosts' arms into actually plugging in probes? (And keeping them plugged in!) Philip -- Philip Paeps Senior Reality Engineer Ministry of Information
