Interesting points. In terms of locating the device, I would imagine most people would keep them in their med/Epi bags--at least that's what I do with our Epi-Pens--I keep them in a case within my bag so I can access them fast if necessary (and labeled in case someone else has to fish them out). My husband keeps his set in a case in his briefcase. If we get the Auvi-Q, I would just put them in there, and maybe get smaller cases. Is it only able to be used with the audio prompts? I thought...
