In my case the use of the puck wasn’t related to a very urgent or critical health issue, but rather seemed a good “low tech” approach for tracking something I’m very curious about regarding my habits / behaviour, and in parallel to gathering quali data in observations - for connecting both sources afterwards. I was naive in assuming the button would work 100% as expected, and even when realising the failures, all the craft work at the end of the process was still valuable to me and contributed to a better understanding of the experience.
Probably it wasn’t that frustrating also because I saw it as a first methodological approach (which I should have prepared and tested better if I could redo things) and in this sense part of my self-experimentation. In any case, I still see it as an useful tool for future interventions (especially after realising the reason for failures), and although I’m not very familiar with this type of instruments I also see it now as a way of “being aware” about specific events as they happen.
