I got one of these for my 97 year old grandmother. The day after she received it, she took a fall in her bathroom. Thankfully, the alarm on the Recorder was loud and shrill enough that it alerted her upstairs neighbors! Without the Emergency Recorder, who knows how long my grandmother could have lain there!!! I STRONGLY URGE anyone whose haselderly or frail people in their family to get an Emergency Recorder!! One never knows what could happen or when...
