These products are no good because they don't work outside the home. When my dad goes for a walk, it doesn't do anything for him. What good is an automated fall detection system if it doesn't work outside of my house? Why can't I put something on my dad's iPhone? I don't get why Philips Lineline doesn't do that. Seems like a no-brainer.
I've found Gold Violin to be a not inexpensive online medical supply store. Sometimes I find cheaper stuff on Amazon and sometimes I find cheaper stuff at my local medical supply store. So Gold Violin is OK but it's not much of a slam dunk.
