First, it wasn't until I committed to the purchase that I was told that the yearly rate would go up considerably after the first year. Second, I did find it a bit more complicated for my 91 year old Dad to comprehend than I was given to believe. We purchased the extra Fall Detection which although a necessary aid, also made explaining how to use the mobile device and the home device more complicated. Now Dad needed to know about 3 different devices. He is terribly worried about an unnecessary call being made by mistake. I didn't even attempt to put up the distress button at this time. Just too many things for Dad to take in all at once. My father is also very deaf, so that complicates matters. We'll see how things go as time goes by.
