This is an absolutely brilliant alarm & far better that the old box style my mother had. If activated, a voice from the call centre can be heard loud & crystal clear through it wherever one is. Despite stating that it might not always be active on some falls I can assure everyone it categorically is. I have twice put the alarm on the bed (not thrown but possibly dropped lightly) & both times the alarm was activated in error & someone answered immediately. Can even take this with me on daily walks which is also an extra comfort. Customer service is also extremely good & everyone is so polite, friendly & helpful. Would highly recommend & have already done so to a relative.
