I have had Mobile Help for over a year. Fortunately I have not had to use the emergency contact. I do. however, have monthly contact with Mobile Help when I perform the monthly check to see that the systems is working. I am pleased with the prompt response to my call. Usually the response comes within 30 seconds of my pressing the call button. I do this on a regular monthly basis. A couple of times I have made these calls away from home while visiting family. I did one from my daughter's house in Chicago. After determining there was no emergency she did a GPS on my location giving the location on her street. She followed that with a statement: "That is the third house from the corner." Another time I placed my call from my sister's home in Cape Giraudoux, Mo. Again, after determining no emergency she did a GPS on the location giving the exact street name and number. Needless to say my family was quite impressed.
