Yeah, I dig. The Reorder button is something they added only a few months ago, and it’s something users have requested for a long time in order to reduce chances of accidental siren activation—especially parents who use these for baby monitors. I guess the good thing is that the siren is supposed to shut itself off after ~30 seconds if you do accidentally bump it, and the app should show you if the siren is actively sounding, but I’m totally with you on wanting to avoid bumping it if at all possible.
Sometimes I’ll use a stylus for touch screens if I’m having problems getting a fingertip to register. When I go to the Red Cross Donor Center in the winter, I try to carry a pen with one of those rubbery stylus tips on the back end with me, because the screen on the check-in notebook doesn’t want to register my cold fingertip.
