they send you a device that plugs into electrical outlet, you press the button they answer: "what is your medical emergency."
I have only tested the device to make sure it is working.
The transformer device they send you has a charge of 6-8 hours in case of a power failure.
I hope if your laying on the kitchen floor and can't hear their response
they would send the ER folks. There supposed to...
They send you a combination lock which fits on front door; the
medical device personnel tells the EM people what the combination is,
there is a house key slot, once combination lock is opened, they now have a key to open your front door.
One of the drawbacks: it is much slower than if you were able to call
EM services yourself. I don't think it is very useful for a major heart attack due to the time lag. However, it is great for falls and if your not
able to get to a telephone.
The emergency device is small, can be worn around you neck or as a wristwatch.
The cost:
low thirties per month, or 105.oo per 3 months. You may be able to obtain something cheaper by shopping around.
