I purchased this for my elderly aunt who had insisted on living alone a while back. She lived in another state. She wouldn't let me pay for a device that had a subscription service. Her daughter (my cousin) was able to set it up but it was a bit complicated. My aunt used it last night 12/19/09. She was rushed to the hospital. She had a heart attack. She was transferred to another hospital with better heart specialists. Unfortunately she passed away this morning but she didn't die alone. Help got to her quickly it was just her time to go. The lord called her home. I recommend it but you do need someone to set up that is good with gadgets. But once setup it's good for life.
