I was in doubt about the need for this devise and found a great deal of confidence in your representatives assistance with this decision. I regrettably was unable to use the devise once it arrived due my decline in my health status. I found that the fall device, around my neck was, what I considered, much to sensitive. When I got it, I put it around my neck and kept working at my computer. It was set off twice within the first hour or so y just bumping it while typing. In retrospect, I guess I would rather reset it several times as opposed to having it not go off when I needed it to. The gentleman that helped when I called to return the unit was very helpful, and asked several very good questions to be sure returning it was the proper option. Thank him for that. The only down side was how long the return label took to get to me. I returned it as soon as I got it because I was concerned that it might have gone pat the trial period. The letter I got confirming it's returned indicted that this was not a concern. Rest assured that I will be a positive proponent of yours to my friends that are in any way in need of your service. Thank you again for your time and concern. God bless you.
