I will agree that it's frustrating to have electronics wig out on us because of the energy gig we got going on. But the upside to digital is that they can make noise to grab your attention, for when angels have a message number for you. No more spending money just to look at a receipt and see if there is a message number for you. The item clicks and squeals when they call. Time to look up and see what 'malfunctioning' numbers flash! Hello, it's angels calling for you!
