Let’s take a moment and define the ideal medical alert system. I’m doing this without reference to any existing system, just so you know.
In my world, an ideal medical alert system would have
a. 24/7 medical alert monitoring at a reasonable cost. I would want to be able to call if I had a non-medical situation and if I had an immediate life-threatening accident. To me, a dollar a day feels entirely reasonable for this.
b. a TWO-WAY pendant for communication. To me this is key. For the people I know, a base station that only works by speakerphone is just too limiting.
c. Pendant range of up to 600 feet. This is a big number, but I feel like this builds in a big margin of error to account for interference or other problems.
d. Waterproof pendant. This means you don’t have to take the pendant off in the shower or bath.
If the cost of 24/7 monitoring was prohibitive, I would recommend a unit that just dials 911.
As noted in the comments (below), it’s hard to find a system that meets all these criteria.
LifeGuardian offers what looks like the LogicMark system but with 24/7 monitoring.
