I had the experience of passing out due to illness and having to struggle to my phone and get help. My Mom told me I needed a button, like she has. I read reviews and Mobile Help has a good rating. They were responsive, good customer service, product delivered quickly, easy to set up and use. Greatest part is the peace of mind in knowing if anything happens again, all I do is push a button and they make the calls, they can direct 911 to my keys, and they have your health care information. Won't have to struggle again is something happens. That's if you can even struggle and make that call. If you live alone, don't wait until something happens. Give yourself peace of mind for that low cost.
